Use replicaof to make a Redis instance a copy of +# another Redis server. A few things to understand ASAP about Redis replication. +# +# +------------------+ +---------------+ +# | Master | ---> | Replica | +# | (receive writes) | | (exact copy) | +# +------------------+ +---------------+ +# +# 1) Redis replication is asynchronous, but you can configure a master to +# stop accepting writes if it appears to be not connected with at least +# a given number of replicas. +# 2) Redis replicas are able to perform a partial resynchronization with the +# master if the replication link is lost for a relatively small amount of +# time. You may want to configure the replication backlog size (see the next +# sections of this file) with a sensible value depending on your needs. +# 3) Replication is automatic and does not need user intervention. After a +# network partition replicas automatically try to reconnect to masters +# and resynchronize with them. +# +# replicaof + +# If the master is password protected (using the "requirepass" configuration +# directive below) it is possible to tell the replica to authenticate before +# starting the replication synchronization process, otherwise the master will +# refuse the replica request. +# +# masterauth +# +# However this is not enough if you are using Redis ACLs (for Redis version +# 6 or greater), and the default user is not capable of running the PSYNC +# command and/or other commands needed for replication. In this case it's +# better to configure a special user to use with replication, and specify the +# masteruser configuration as such: +# +# masteruser +# +# When masteruser is specified, the replica will authenticate against its +# master using the new AUTH form: AUTH . + +# When a replica loses its connection with the master, or when the replication +# is still in progress, the replica can act in two different ways: +# +# 1) if replica-serve-stale-data is set to 'yes' (the default) the replica will +# still reply to client requests, possibly with out of date data, or the +# data set may just be empty if this is the first synchronization. +# +# 2) If replica-serve-stale-data is set to 'no' the replica will reply with error +# "MASTERDOWN Link with MASTER is down and replica-serve-stale-data is set to 'no'" +# to all data access commands, excluding commands such as: +# INFO, REPLICAOF, AUTH, SHUTDOWN, REPLCONF, ROLE, CONFIG, SUBSCRIBE, +# UNSUBSCRIBE, PSUBSCRIBE, PUNSUBSCRIBE, PUBLISH, PUBSUB, COMMAND, POST, +# HOST and LATENCY. +# +replica-serve-stale-data yes + +# You can configure a replica instance to accept writes or not. Writing against +# a replica instance may be useful to store some ephemeral data (because data +# written on a replica will be easily deleted after resync with the master) but +# may also cause problems if clients are writing to it because of a +# misconfiguration. +# +# Since Redis 2.6 by default replicas are read-only. +# +# Note: read only replicas are not designed to be exposed to untrusted clients +# on the internet. It's just a protection layer against misuse of the instance. +# Still a read only replica exports by default all the administrative commands +# such as CONFIG, DEBUG, and so forth. To a limited extent you can improve +# security of read only replicas using 'rename-command' to shadow all the +# administrative / dangerous commands. +replica-read-only yes + +# Replication SYNC strategy: disk or socket. +# +# New replicas and reconnecting replicas that are not able to continue the +# replication process just receiving differences, need to do what is called a +# "full synchronization". An RDB file is transmitted from the master to the +# replicas. +# +# The transmission can happen in two different ways: +# +# 1) Disk-backed: The Redis master creates a new process that writes the RDB +# file on disk. Later the file is transferred by the parent +# process to the replicas incrementally. +# 2) Diskless: The Redis master creates a new process that directly writes the +# RDB file to replica sockets, without touching the disk at all. +# +# With disk-backed replication, while the RDB file is generated, more replicas +# can be queued and served with the RDB file as soon as the current child +# producing the RDB file finishes its work. With diskless replication instead +# once the transfer starts, new replicas arriving will be queued and a new +# transfer will start when the current one terminates. +# +# When diskless replication is used, the master waits a configurable amount of +# time (in seconds) before starting the transfer in the hope that multiple +# replicas will arrive and the transfer can be parallelized. +# +# With slow disks and fast (large bandwidth) networks, diskless replication +# works better. +repl-diskless-sync yes + +# When diskless replication is enabled, it is possible to configure the delay +# the server waits in order to spawn the child that transfers the RDB via socket +# to the replicas. +# +# This is important since once the transfer starts, it is not possible to serve +# new replicas arriving, that will be queued for the next RDB transfer, so the +# server waits a delay in order to let more replicas arrive. +# +# The delay is specified in seconds, and by default is 5 seconds.

In turn +# this is used in order to send invalidation messages to clients. Please +# check this page to understand more about the feature: +# +# https://redis.io/topics/client-side-caching +# +# When tracking is enabled for a client, all the read only queries are assumed +# to be cached: this will force Redis to store information in the invalidation +# table. When keys are modified, such information is flushed away, and +# invalidation messages are sent to the clients. However if the workload is +# heavily dominated by reads, Redis could use more and more memory in order +# to track the keys fetched by many clients. +# +# For this reason it is possible to configure a maximum fill value for the +# invalidation table. By default it is set to 1M of keys, and once this limit +# is reached, Redis will start to evict keys in the invalidation table +# even if they were not modified, just to reclaim memory: this will in turn +# force the clients to invalidate the cached values. Basically the table +# maximum size is a trade off between the memory you want to spend server +# side to track information about who cached what, and the ability of clients +# to retain cached objects in memory. +# +# If you set the value to 0, it means there are no limits, and Redis will +# retain as many keys as needed in the invalidation table. +# In the "stats" INFO section, you can find information about the number of +# keys in the invalidation table at every given moment. +# +# Note: when key tracking is used in broadcasting mode, no memory is used +# in the server side so this setting is useless. +# +# tracking-table-max-keys 1000000 + +################################## SECURITY ################################### + +# Warning: since Redis is pretty fast, an outside user can try up to +# 1 million passwords per second against a modern box.

Otherwise if the "default" user is not flagged with "nopass" +# the connections will start in not authenticated state, and will require +# AUTH (or the HELLO command AUTH option) in order to be authenticated and +# start to work. +# +# The ACL rules that describe what a user can do are the following: +# +# on Enable the user: it is possible to authenticate as this user. +# off Disable the user: it's no longer possible to authenticate +# with this user, however the already authenticated connections +# will still work. +# skip-sanitize-payload RESTORE dump-payload sanitization is skipped. +# sanitize-payload RESTORE dump-payload is sanitized (default). +# + Allow the execution of that command. +# May be used with `|` for allowing subcommands (e.g "+config|get") +# - Disallow the execution of that command. +# May be used with `|` for blocking subcommands (e.g "-config|set") +# +@ Allow the execution of all the commands in such category +# with valid categories are like @admin, @set, @sortedset, ... +# and so forth, see the full list in the server.c file where +# the Redis command table is described and defined. +# The special category @all means all the commands, but currently +# present in the server, and that will be loaded in the future +# via modules. +# +|first-arg Allow a specific first argument of an otherwise +# disabled command. It is only supported on commands with +# no sub-commands, and is not allowed as negative form +# like -SELECT|1, only additive starting with "+". This +# feature is deprecated and may be removed in the future. +# allcommands Alias for +@all. Note that it implies the ability to execute +# all the future commands loaded via the modules system. +# nocommands Alias for -@all. +# ~ Add a pattern of keys that can be mentioned as part of +# commands. For instance ~* allows all the keys. The pattern +# is a glob-style pattern like the one of KEYS. +# It is possible to specify multiple patterns. +# %R~ Add key read pattern that specifies which keys can be read +# from. +# %W~ Add key write pattern that specifies which keys can be +# written to. +# allkeys Alias for ~* +# resetkeys Flush the list of allowed keys patterns. +# & Add a glob-style pattern of Pub/Sub channels that can be +# accessed by the user.

If this directive is +# used for the default user, every new connection will be +# immediately authenticated with the default user without +# any explicit AUTH command required. Note that the "resetpass" +# directive will clear this condition. +# resetpass Flush the list of allowed passwords. Moreover removes the +# "nopass" status. After "resetpass" the user has no associated +# passwords and there is no way to authenticate without adding +# some password (or setting it as "nopass" later). +# reset Performs the following actions: resetpass, resetkeys, off, +# -@all.

However note that the additive +# and subtractive rules will CHANGE MEANING depending on the ordering. +# For instance see the following example: +# +# user alice on +@all -DEBUG ~* >somepassword +# +# This will allow "alice" to use all the commands with the exception of the +# DEBUG command, since +@all added all the commands to the set of the commands +# alice can use, and later DEBUG was removed. However if we invert the order +# of two ACL rules the result will be different: +# +# user alice on -DEBUG +@all ~* >somepassword +# +# Now DEBUG was removed when alice had yet no commands in the set of allowed +# commands, later all the commands are added, so the user will be able to +# execute everything. +# +# Basically ACL rules are processed left-to-right. +# +# The following is a list of command categories and their meanings: +# * keyspace - Writing or reading from keys, databases, or their metadata +# in a type agnostic way. Includes DEL, RESTORE, DUMP, RENAME, EXISTS, DBSIZE, +# KEYS, EXPIRE, TTL, FLUSHALL, etc. Commands that may modify the keyspace, +# key or metadata will also have `write` category. Commands that only read +# the keyspace, key or metadata will have the `read` category. +# * read - Reading from keys (values or metadata). Note that commands that don't +# interact with keys, will not have either `read` or `write`. +# * write - Writing to keys (values or metadata) +# * admin - Administrative commands. Normal applications will never need to use +# these. Includes REPLICAOF, CONFIG, DEBUG, SAVE, MONITOR, ACL, SHUTDOWN, etc. +# * dangerous - Potentially dangerous (each should be considered with care for +# various reasons). This includes FLUSHALL, MIGRATE, RESTORE, SORT, KEYS, +# CLIENT, DEBUG, INFO, CONFIG, SAVE, REPLICAOF, etc. +# * connection - Commands affecting the connection or other connections. +# This includes AUTH, SELECT, COMMAND, CLIENT, ECHO, PING, etc. +# * blocking - Potentially blocking the connection until released by another +# command. +# * fast - Fast O(1) commands. May loop on the number of arguments, but not the +# number of elements in the key. +# * slow - All commands that are not Fast. +# * pubsub - PUBLISH / SUBSCRIBE related +# * transaction - WATCH / MULTI / EXEC related commands. +# * scripting - Scripting related. +# * set - Data type: sets related. +# * sortedset - Data type: zsets related. +# * list - Data type: lists related. +# * hash - Data type: hashes related. +# * string - Data type: strings related. +# * bitmap - Data type: bitmaps related. +# * hyperloglog - Data type: hyperloglog related. +# * geo - Data type: geo related. +# * stream - Data type: streams related. +# +# For more information about ACL configuration please refer to +# the Redis web site at https://redis.io/topics/acl + +# ACL LOG +# +# The ACL Log tracks failed commands and authentication events associated +# with ACLs.

It is important to size the +# limit accordingly in case of very large clusters. +# +# maxclients 10000 + +############################## MEMORY MANAGEMENT ################################ + +# Set a memory usage limit to the specified amount of bytes. +# When the memory limit is reached Redis will try to remove keys +# according to the eviction policy selected (see maxmemory-policy). +# +# If Redis can't remove keys according to the policy, or if the policy is +# set to 'noeviction', Redis will start to reply with errors to commands +# that would use more memory, like SET, LPUSH, and so on, and will continue +# to reply to read-only commands like GET. +# +# This option is usually useful when using Redis as an LRU or LFU cache, or to +# set a hard memory limit for an instance (using the 'noeviction' policy). +# +# WARNING: If you have replicas attached to an instance with maxmemory on, +# the size of the output buffers needed to feed the replicas are subtracted +# from the used memory count, so that network problems / resyncs will +# not trigger a loop where keys are evicted, and in turn the output +# buffer of replicas is full with DELs of keys evicted triggering the deletion +# of more keys, and so forth until the database is completely emptied. +# +# In short... if you have replicas attached it is suggested that you set a lower +# limit for maxmemory so that there is some free RAM on the system for replica +# output buffers (but this is not needed if the policy is 'noeviction'). +# +# maxmemory + +# MAXMEMORY POLICY: how Redis will select what to remove when maxmemory +# is reached. You can select one from the following behaviors: +# +# volatile-lru -> Evict using approximated LRU, only keys with an expire set. +# allkeys-lru -> Evict any key using approximated LRU. +# volatile-lfu -> Evict using approximated LFU, only keys with an expire set. +# allkeys-lfu -> Evict any key using approximated LFU. +# volatile-random -> Remove a random key having an expire set. +# allkeys-random -> Remove a random key, any key. +# volatile-ttl -> Remove the key with the nearest expire time (minor TTL) +# noeviction -> Don't evict anything, just return an error on write operations. +# +# LRU means Least Recently Used +# LFU means Least Frequently Used +# +# Both LRU, LFU and volatile-ttl are implemented using approximated +# randomized algorithms. +# +# Note: with any of the above policies, when there are no suitable keys for +# eviction, Redis will return an error on write operations that require +# more memory. These are usually commands that create new keys, add data or +# modify existing keys. A few examples are: SET, INCR, HSET, LPUSH, SUNIONSTORE, +# SORT (due to the STORE argument), and EXEC (if the transaction includes any +# command that requires memory). +# +# The default is: +# +# maxmemory-policy noeviction + +# LRU, LFU and minimal TTL algorithms are not precise algorithms but approximated +# algorithms (in order to save memory), so you can tune it for speed or +# accuracy. By default Redis will check five keys and pick the one that was +# used least recently, you can change the sample size using the following +# configuration directive. +# +# The default of 5 produces good enough results. 10 Approximates very closely +# true LRU but costs more CPU. 3 is faster but not very accurate. +# +# maxmemory-samples 5 + +# Eviction processing is designed to function well with the default setting. +# If there is an unusually large amount of write traffic, this value may need to +# be increased. Decreasing this value may reduce latency at the risk of +# eviction processing effectiveness +# 0 = minimum latency, 10 = default, 100 = process without regard to latency +# +# maxmemory-eviction-tenacity 10 + +# Starting from Redis 5, by default a replica will ignore its maxmemory setting +# (unless it is promoted to master after a failover or manually). It means +# that the eviction of keys will be just handled by the master, sending the +# DEL commands to the replica as keys evict in the master side. +# +# This behavior ensures that masters and replicas stay consistent, and is usually +# what you want, however if your replica is writable, or you want the replica +# to have a different memory setting, and you are sure all the writes performed +# to the replica are idempotent, then you may change this default (but be sure +# to understand what you are doing). +# +# Note that since the replica by default does not evict, it may end using more +# memory than the one set via maxmemory (there are certain buffers that may +# be larger on the replica, or data structures may sometimes take more memory +# and so forth). So make sure you monitor your replicas and make sure they +# have enough memory to never hit a real out-of-memory condition before the +# master hits the configured maxmemory setting. +# +# replica-ignore-maxmemory yes + +# Redis reclaims expired keys in two ways: upon access when those keys are +# found to be expired, and also in background, in what is called the +# "active expire key". The key space is slowly and interactively scanned +# looking for expired keys to reclaim, so that it is possible to free memory +# of keys that are expired and will never be accessed again in a short time. +# +# The default effort of the expire cycle will try to avoid having more than +# ten percent of expired keys still in memory, and will try to avoid consuming +# more than 25% of total memory and to add latency to the system. However +# it is possible to increase the expire "effort" that is normally set to +# "1", to a greater value, up to the value "10". At its maximum value the +# system will use more CPU, longer cycles (and technically may introduce +# more latency), and will tolerate less already expired keys still present +# in the system. It's a tradeoff between memory, CPU and latency. +# +# active-expire-effort 1 + +############################# LAZY FREEING #################################### + +# Redis has two primitives to delete keys. One is called DEL and is a blocking +# deletion of the object. It means that the server stops processing new commands +# in order to reclaim all the memory associated with an object in a synchronous +# way. If the key deleted is associated with a small object, the time needed +# in order to execute the DEL command is very small and comparable to most other +# O(1) or O(log_N) commands in Redis. However if the key is associated with an +# aggregated value containing millions of elements, the server can block for +# a long time (even seconds) in order to complete the operation. +# +# For the above reasons Redis also offers non blocking deletion primitives +# such as UNLINK (non blocking DEL) and the ASYNC option of FLUSHALL and +# FLUSHDB commands, in order to reclaim memory in background. Those commands +# are executed in constant time. Another thread will incrementally free the +# object in the background as fast as possible. +# +# DEL, UNLINK and ASYNC option of FLUSHALL and FLUSHDB are user-controlled. +# It's up to the design of the application to understand when it is a good +# idea to use one or the other. However the Redis server sometimes has to +# delete keys or flush the whole database as a side effect of other operations. +# Specifically Redis deletes objects independently of a user call in the +# following scenarios: +# +# 1) On eviction, because of the maxmemory and maxmemory policy configurations, +# in order to make room for new data, without going over the specified +# memory limit. +# 2) Because of expire: when a key with an associated time to live (see the +# EXPIRE command) must be deleted from memory. +# 3) Because of a side effect of a command that stores data on a key that may +# already exist. For example the RENAME command may delete the old key +# content when it is replaced with another one. Similarly SUNIONSTORE +# or SORT with STORE option may delete existing keys. The SET command +# itself removes any old content of the specified key in order to replace +# it with the specified string. +# 4) During replication, when a replica performs a full resynchronization with +# its master, the content of the whole database is removed in order to +# load the RDB file just transferred. +# +# In all the above cases the default is to delete objects in a blocking way, +# like if DEL was called. However you can configure each case specifically +# in order to instead release memory in a non-blocking way like if UNLINK +# was called, using the following configuration directives. + +lazyfree-lazy-eviction no +lazyfree-lazy-expire no +lazyfree-lazy-server-del no +replica-lazy-flush no + +# It is also possible, for the case when to replace the user code DEL calls +# with UNLINK calls is not easy, to modify the default behavior of the DEL +# command to act exactly like UNLINK, using the following configuration +# directive: + +lazyfree-lazy-user-del no + +# FLUSHDB, FLUSHALL, SCRIPT FLUSH and FUNCTION FLUSH support both asynchronous and synchronous +# deletion, which can be controlled by passing the [SYNC|ASYNC] flags into the +# commands. When neither flag is passed, this directive will be used to determine +# if the data should be deleted asynchronously. + +lazyfree-lazy-user-flush no + +################################ THREADED I/O ################################# + +# Redis is mostly single threaded, however there are certain threaded +# operations such as UNLINK, slow I/O accesses and other things that are +# performed on side threads. +# +# Now it is also possible to handle Redis clients socket reads and writes +# in different I/O threads. Since especially writing is so slow, normally +# Redis users use pipelining in order to speed up the Redis performances per +# core, and spawn multiple instances in order to scale more. Using I/O +# threads it is possible to easily speedup two times Redis without resorting +# to pipelining nor sharding of the instance. +# +# By default threading is disabled, we suggest enabling it only in machines +# that have at least 4 or more cores, leaving at least one spare core. +# Using more than 8 threads is unlikely to help much. We also recommend using +# threaded I/O only if you actually have performance problems, with Redis +# instances being able to use a quite big percentage of CPU time, otherwise +# there is no point in using this feature. +# +# So for instance if you have a four cores boxes, try to use 2 or 3 I/O +# threads, if you have a 8 cores, try to use 6 threads. In order to +# enable I/O threads use the following configuration directive: +# +# io-threads 4 +# +# Setting io-threads to 1 will just use the main thread as usual. +# When I/O threads are enabled, we only use threads for writes, that is +# to thread the write(2) syscall and transfer the client buffers to the +# socket. However it is also possible to enable threading of reads and +# protocol parsing using the following configuration directive, by setting +# it to yes: +# +# io-threads-do-reads no +# +# Usually threading reads doesn't help much. +# +# NOTE 1: This configuration directive cannot be changed at runtime via +# CONFIG SET. Also, this feature currently does not work when SSL is +# enabled. +# +# NOTE 2: If you want to test the Redis speedup using redis-benchmark, make +# sure you also run the benchmark itself in threaded mode, using the +# --threads option to match the number of Redis threads, otherwise you'll not +# be able to notice the improvements. + +############################ KERNEL OOM CONTROL ############################## + +# On Linux, it is possible to hint the kernel OOM killer on what processes +# should be killed first when out of memory. +# +# Enabling this feature makes Redis actively control the oom_score_adj value +# for all its processes, depending on their role. The default scores will +# attempt to have background child processes killed before all others, and +# replicas killed before masters. +# +# Redis supports these options: +# +# no: Don't make changes to oom-score-adj (default). +# yes: Alias to "relative" see below. +# absolute: Values in oom-score-adj-values are written as is to the kernel. +# relative: Values are used relative to the initial value of oom_score_adj when +# the server starts and are then clamped to a range of -1000 to 1000. +# Because typically the initial value is 0, they will often match the +# absolute values. +oom-score-adj no + +# When oom-score-adj is used, this directive controls the specific values used +# for master, replica and background child processes. Values range -2000 to +# 2000 (higher means more likely to be killed). +# +# Unprivileged processes (not root, and without CAP_SYS_RESOURCE capabilities) +# can freely increase their value, but not decrease it below its initial +# settings.

For instance using the default data fsync policy +# (see later in the config file) Redis can lose just one second of writes in a +# dramatic event like a server power outage, or a single write if something +# wrong with the Redis process itself happens, but the operating system is +# still running correctly. +# +# AOF and RDB persistence can be enabled at the same time without problems. +# If the AOF is enabled on startup Redis will load the AOF, that is the file +# with the better durability guarantees. +# +# Please check https://redis.io/topics/persistence for more information. + +appendonly no + +# The base name of the append only file. +# +# Redis 7 and newer use a set of append-only files to persist the dataset +# and changes applied to it. There are two basic types of files in use: +# +# - Base files, which are a snapshot representing the complete state of the +# dataset at the time the file was created. Base files can be either in +# the form of RDB (binary serialized) or AOF (textual commands). +# - Incremental files, which contain additional commands that were applied +# to the dataset following the previous file. +# +# In addition, manifest files are used to track the files and the order in +# which they were created and should be applied. +# +# Append-only file names are created by Redis following a specific pattern. +# The file name's prefix is based on the 'appendfilename' configuration +# parameter, followed by additional information about the sequence and type. +# +# For example, if appendfilename is set to appendonly.aof, the following file +# names could be derived: +# +# - appendonly.aof.1.base.rdb as a base file. +# - appendonly.aof.1.incr.aof, appendonly.aof.2.incr.aof as incremental files. +# - appendonly.aof.manifest as a manifest file. + +appendfilename "appendonly.aof" + +# For convenience, Redis stores all persistent append-only files in a dedicated +# directory.

This can be the last ping or command received (if the master +# is still in the "connected" state), or the time that elapsed since the +# disconnection with the master (if the replication link is currently down). +# If the last interaction is too old, the replica will not try to failover +# at all. +# +# The point "2" can be tuned by user. Specifically a replica will not perform +# the failover if, since the last interaction with the master, the time +# elapsed is greater than: +# +# (node-timeout * cluster-replica-validity-factor) + repl-ping-replica-period +# +# So for example if node-timeout is 30 seconds, and the cluster-replica-validity-factor +# is 10, and assuming a default repl-ping-replica-period of 10 seconds, the +# replica will not try to failover if it was not able to talk with the master +# for longer than 310 seconds. +# +# A large cluster-replica-validity-factor may allow replicas with too old data to failover +# a master, while a too small value may prevent the cluster from being able to +# elect a replica at all. +# +# For maximum availability, it is possible to set the cluster-replica-validity-factor +# to a value of 0, which means, that replicas will always try to failover the +# master regardless of the last time they interacted with the master. +# (However they'll always try to apply a delay proportional to their +# offset rank). +# +# Zero is the only value able to guarantee that when all the partitions heal +# the cluster will always be able to continue. +# +# cluster-replica-validity-factor 10 + +# Cluster replicas are able to migrate to orphaned masters, that are masters +# that are left without working replicas.

However thanks to this feature +# implemented by Oran Agra for Redis 4.0 this process can happen at runtime +# in a "hot" way, while the server is running. +# +# Basically when the fragmentation is over a certain level (see the +# configuration options below) Redis will start to create new copies of the +# values in contiguous memory regions by exploiting certain specific Jemalloc +# features (in order to understand if an allocation is causing fragmentation +# and to allocate it in a better place), and at the same time, will release the +# old copies of the data. This process, repeated incrementally for all the keys +# will cause the fragmentation to drop back to normal values. +# +# Important things to understand: +# +# 1. This feature is disabled by default, and only works if you compiled Redis +# to use the copy of Jemalloc we ship with the source code of Redis. +# This is the default with Linux builds. +# +# 2. You never need to enable this feature if you don't have fragmentation +# issues. +# +# 3. Once you experience fragmentation, you can enable this feature when +# needed with the command "CONFIG SET activedefrag yes". +# +# The configuration parameters are able to fine tune the behavior of the +# defragmentation process. If you are not sure about what they mean it is +# a good idea to leave the defaults untouched. + +# Active defragmentation is disabled by default +# activedefrag no + +# Minimum amount of fragmentation waste to start active defrag +# active-defrag-ignore-bytes 100mb + +# Minimum percentage of fragmentation to start active defrag +# active-defrag-threshold-lower 10 + +# Maximum percentage of fragmentation at which we use maximum effort +# active-defrag-threshold-upper 100 + +# Minimal effort for defrag in CPU percentage, to be used when the lower +# threshold is reached +# active-defrag-cycle-min 1 + +# Maximal effort for defrag in CPU percentage, to be used when the upper +# threshold is reached +# active-defrag-cycle-max 25 + +# Maximum number of set/hash/zset/list fields that will be processed from +# the main dictionary scan +# active-defrag-max-scan-fields 1000 + +# Jemalloc background thread for purging will be enabled by default +jemalloc-bg-thread yes + +# It is possible to pin different threads and processes of Redis to specific +# CPUs in your system, in order to maximize the performances of the server. +# This is useful both in order to pin different Redis threads in different +# CPUs, but also in order to make sure that multiple Redis instances running +# in the same host will be pinned to different CPUs. +# +# Normally you can do this using the "taskset" command, however it is also +# possible to this via Redis configuration directly, both in Linux and FreeBSD. +# +# You can pin the server/IO threads, bio threads, aof rewrite child process, and +# the bgsave child process.
