Added S3 Tables design doc - #9968
Conversation
Signed-off-by: Danny Zaken <dannyzaken@gmail.com>
📝 WalkthroughWalkthroughThe design document specifies a Developer Preview implementation for S3 Tables in NooBaa. It covers shared SDK architecture, persistence, REST protocols, Iceberg metadata commits, authentication, authorization, deployment wiring, testing, and deferred functionality. ChangesS3 Tables design
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to The proposed S3 Tables design still permits scenarios that could cause data corruption, inconsistent table-bucket state, authorization errors, or endpoint outages during implementation. The lifecycle, metadata integrity, resource identity, row-ID arithmetic, API contract, and request-bounding rules should be resolved before this design is merged. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

In `@docs/design/s3-tables-design.md`:
- Around line 1224-1233: The worker lifecycle design must bound aggregate
metadata-transform backlog, not just individual document size. Add a per-fork
in-flight and queued-request limit before buffering request bodies, reject
excess requests with explicit 429 or 503 backpressure, and cover concurrent
requests at the metadata-size limit in tests; apply the same constraint to the
related section near the later worker handling.
- Around line 795-800: Make create_table_bucket and delete_table_bucket
failure-atomic by introducing a durable provisioning/deletion state or core-side
transaction that keeps the backing bucket guarded throughout each lifecycle
transition. Ensure compensation is idempotent, verifies the backing-bucket
identity before destructive cleanup, and prevents configuration or deletion
requests from acting on buckets with incomplete transitions. Add
failure-injection tests covering every create and delete boundary.
- Around line 431-435: Update the UpdateTableMetadataLocation design to
explicitly define handling for .metadata.json.gz files: either document
Developer Preview compression as unsupported and require a 400 response, or
specify worker decompression and add compressed metadata coverage to the client
matrix. Keep the documented filename and write-then-swap behavior consistent
with the chosen policy.
- Around line 833-839: Update set_table_metadata_location to run the shared
metadata validation before _swap_pointer, including table UUID and location
containment, write-path validation, format-version limits, and v3 row-lineage
checks for the new snapshot’s first-row-id and next-row-id; reuse the commit
path’s size cap and worker discipline.
- Around line 867-887: Define the BucketSpace contract for
update_table_metadata_location across the API, types, and facade declarations,
using one consistent operation name. Specify request and response shapes,
including the server-generated token, distinguish zero-row conflicts from
missing-table results, and document NSFS/RPC error mappings. Preserve an unknown
commit state when a timeout occurs after token issuance, and add contract tests
for both facades covering concurrent deletion and transport failure.
- Around line 533-556: Update the design to explicitly document that
table-bucket identity is restricted to {system, name}, excluding owner/account
and Region, or revise resolution, uniqueness, and backing-bucket identity to
include those fields. Build table resource ARNs using the stable table record ID
with the /table/<table-id> path rather than the rename-sensitive namespace/table
path, and add authorization tests covering same-name buckets across accounts and
Regions plus table renames.
- Around line 1126-1140: The v3 row-ID arithmetic must preserve Iceberg long
values beyond Number.MAX_SAFE_INTEGER. Update the add-snapshot logic using
first-row-id, added-rows, and next-row-id to use lossless integer handling end
to end, including JSON parsing/serialization, or explicitly reject unsafe
values; avoid Number-based Math.max and addition. Add tests covering safe
boundaries and overflow/unsafe inputs.
- Around line 377-380: Update set_table_metadata_location and _swap_pointer so
the pointer swap is bound to the exact validated metadata bytes rather than only
the location and version token; use a server-owned immutable copy, immutable
object version, or an enforced content hash, and ensure subsequent reads
validate or retrieve that bound content.

Bind validated metadata bytes to the pointer swap.
set_table_metadata_location validates a client-supplied object, but _swap_pointer stores only its location and version token. Because ordinary PutObject can replace an existing key without conditions, the object can change before or after the swap. Bind the pointer to immutable content with a server-owned immutable copy, an object version, or a content hash enforced on reads.

AWS S3 Tables UpdateTableMetadataLocation metadataLocation .metadata.json.gz allowed
💡 Result:
Yes, using.metadata.json.gz for the metadata location in AWS S3 Tables is allowed and officially supported for Apache Iceberg tables [1][2][3][4]. When calling the UpdateTableMetadataLocation operation, the provided metadata location must be an S3 URI that begins with the table's warehouse location [1][3]. For Apache Iceberg tables, this URI must end in.metadata.json, or if the metadata file is Gzip-compressed,.metadata.json.gz [1][2][5].

Handle compressed Iceberg metadata explicitly. UpdateTableMetadataLocation accepts .metadata.json.gz, but this design accepts only .metadata.json. If compression is unsupported in the Developer Preview, document the limitation and return 400; otherwise, decompress compressed metadata in the worker and add it to the client matrix.

| **Decision.** Every IRC URL carries a free-form `{prefix}` segment; in AWS's dialect | ||
| it is the percent-encoded table bucket ARN. The parser is **permissive on input, | ||
| canonical on output**: after percent-decoding, accept | ||
| `arn:aws:s3tables:<region>:<account>:bucket/<name>` with region and account optional | ||
| or empty, and also accept a bare `<name>`. Region and account are ignored - there is | ||
| one system, and the caller's identity comes from the SigV4 credential. The **table | ||
| bucket name is the key**. | ||
|
|
||
| AWS's documented client configurations put the full ARN in the `warehouse` property, | ||
| so accepting it verbatim means a user changes only the endpoint URL. Permissiveness | ||
| costs one regular expression and guarantees we never have to break a client. | ||
|
|
||
| Two ARN shapes stay distinct, because different code consumes them: | ||
|
|
||
| | Purpose | Shape | | ||
| |---|---| | ||
| | IRC `{prefix}` and S3Tables ARN paths (client-facing) | `arn:aws:s3tables:<region>:<account>:bucket/<name>`, percent-encoded | | ||
| | Authorization resource (internal) | `arn:aws:s3tables:::<table-bucket>` and `arn:aws:s3tables:::<table-bucket>/<namespace>/<table>` | | ||
|
|
||
| The internal shape comes free: `iam_utils._get_resource_arn_from_req` builds | ||
| `arn:aws:${service}:::${bucket_name}` and appends `/${req.params.key}` when set | ||
| (`src/endpoint/iam/iam_utils.js:1326-1334`), mirroring the vector service's flat | ||
| `arn:aws:s3vectors:::<name>` (`src/endpoint/vector/vector_rest.js:296`). Setting the | ||
| key to `<namespace>/<table>` yields the two-level resource ARN with no new code. |

AWS S3 Tables service authorization table bucket ARN table ARN stable table ID account region
💡 Result:
Amazon S3 Tables is an S3 storage feature that uses the s3tables service namespace for its resources [1]. Access management for S3 Tables is handled via AWS Identity and Access Management (IAM) and resource-based policies [1][2]. Resource ARN Formats S3 Tables resources follow these Amazon Resource Name (ARN) formats [3][4][5]: Table Bucket ARN: arn:aws:s3tables:{region}:{owner-account-id}:bucket/{bucket-name} [4][5] Table ARN: arn:aws:s3tables:{region}:{owner-account-id}:bucket/{bucket-name}/table/{table-id} [3][4] Key Concepts - Table ID: Each table is identified by a unique table ID [4]. While tables can be renamed, they retain their unique ARN and table ID [4]. - Authorization: S3 Tables utilizes the s3tables service namespace, allowing for specialized IAM policies [1]. You can grant access at the bucket, namespace, or individual table level [1][2]. When a request is made, S3 Tables evaluates all relevant policies—including IAM user/role policies, table bucket policies, and table-specific policies—to determine authorization [2]. - Integration: S3 Tables are typically used for tabular data in the Apache Iceberg format and can be integrated with AWS analytics services via the AWS Glue Data Catalog [1][6].

Define the NooBaa-to-AWS resource identity mapping.
The design stores owner but uses {system, name} as the unique table-bucket key, derives the backing bucket from name, and ignores ARN account and Region. It cannot represent AWS-valid same-name buckets from different accounts or Regions. Document this restriction, or include owner/account and Region in resolution, uniqueness, and backing-bucket identity.
Use the stable table record ID in table resource ARNs. The proposed <namespace>/<table> path changes after a rename, but AWS uses /table/<table-id> and keeps the ARN stable. Test same-name, cross-account, cross-Region, and rename authorization.

Make table-bucket lifecycle operations failure-atomic.
create_table_bucket creates the ordinary backing bucket before the authoritative table_buckets record. During this interval, the guard in Lines 1307-1313 cannot identify the bucket, so bucket configuration or deletion requests can succeed. If the record write then fails, the compensation can delete a bucket that was already modified.
delete_table_bucket has the reverse failure window. Deleting the record first removes the guard if bucket deletion fails. Deleting the bucket first can leave a dangling record.
Use a durable provisioning/deletion state or a core-side transaction. Make compensation idempotent and verify the backing-bucket identity before destructive cleanup. Add failure-injection tests for every boundary.

| is the feature, not a formality**. It must confirm the location lies within that | ||
| table's own prefix, ends in `.metadata.json`, exists, and contains a `table-uuid` | ||
| matching the record. Without the prefix check, a caller could aim a table at | ||
| arbitrary bytes; without the uuid check, at a different table in the same backing | ||
| bucket. The uuid check means fetching a document that can reach 50 MB, so it takes | ||
| the same size cap and worker discipline as the commit path (§8.3). |

Apache Iceberg table format specification v3 first-row-id next-row-id commit attempt added-rows
💡 Result:
In Apache Iceberg table format v3, row lineage is tracked to provide a unique, persistent identity for rows, enabling efficient change tracking and updates [1][2][3]. The following mechanisms manage this lineage: Next-Row-ID The next-row-id is a required field at the table metadata level in v3 [1][4]. It acts as a counter that tracks the next available row ID to be assigned. When a table is upgraded to v3, this value is initialized to 0 [1][5]. During a commit, the table's next-row-id is advanced based on the number of rows added in the new snapshot [6][7]. Specifically, it increments by the total number of rows newly assigned IDs in that commit (often referred to as added-rows in implementation) [6][7]. First-Row-ID Each snapshot, data manifest, and data file uses a first_row_id to establish the starting ID for its rows [1][8]. - Snapshot: Upon creating an append snapshot, its first-row-id is set to the current next-row-id of the table [1][9]. - Manifest and Data File: The first_row_id for manifests and data files is assigned via inheritance [1]. For a data file, the _row_id for the first row is its first_row_id, and subsequent rows are identified as first_row_id + _pos (where _pos is the row's position in the file) [1][8]. Commit Attempt and Added-Rows During the commit process, engines must assign row IDs to all added and existing data files that do not yet have an assigned first_row_id [1][4]. - When writing a manifest list, the engine assigns a first_row_id to each data manifest [1]. - The number of rows effectively "consumed" from the ID space by a snapshot is determined by the added-rows count, which is calculated from the manifest-list writer's assigned row-ID delta (the difference between the next available ID after the snapshot and the snapshot's starting first-row-id) [6][5]. - This ensures that every row in the table can be uniquely identified, and the next-row-id remains synchronized across concurrent commits [1][7][10]. If a concurrent commit advances the next-row-id, subsequent commit attempts may fail if they rely on stale metadata, requiring a refresh and re-application of the changes [10].

| ### 6.3 What `BucketSpace` gains | ||
|
|
||
| The SDK reaches persistence only through these, added alongside the existing | ||
| vector-bucket methods (`src/sdk/nb.d.ts:915-975`): | ||
|
|
||
| | Method | Containerized (`bucketspace_nb`) | NSFS (`bucketspace_fs`) | | ||
| |---|---|---| | ||
| | `create_table_bucket` / `get_table_bucket` / `list_table_buckets` / `delete_table_bucket` | RPC → `system_store` collection | `config_fs` records | | ||
| | `create_table_namespace` / `get_table_namespace` / `list_table_namespaces` / `delete_table_namespace` | RPC → dedicated collection | `config_fs` records | | ||
| | `create_table` / `get_table` / `list_tables` / `delete_table` / `rename_table` | RPC → dedicated collection | `config_fs` records | | ||
| | **`update_table_metadata_location`** | RPC → conditional update, `rowCount ∈ {0,1}` | `safe_link` guarded by `(mtime, ino)` | | ||
|
|
||
| Every containerized method becomes a new `bucket_api` operation implemented in | ||
| `bucket_server`, mirroring how vector-bucket operations are declared | ||
| (`src/api/bucket_api.js:979-998`) and served | ||
| (`src/server/system_services/bucket_server.js:2307-2343`). | ||
|
|
||
| **The swap is a declared capability, not an assumption.** `BucketSpace` | ||
| implementations that cannot perform a conditional update must say so rather than | ||
| degrade to last-writer-wins, and the SDK must refuse commits there. Silent | ||
| degradation here is table corruption. |

Define the BucketSpace swap contract before implementation.
The design defines protocol outcomes but not the BucketSpace contract. update_table_metadata_location has no API, type, or facade declaration, and the documented request uses the different name set_table_metadata_location.
Define the request and response, including the server-generated token, zero-row conflict versus missing-table results, and NSFS and RPC error mapping. Preserve an unknown commit state when a swap timeout occurs after issuance. Add contract tests for both facades, including concurrent deletion and transport failure.

Bound the metadata-transform backlog.
The 50 MB limit applies to one document, not to the pending-request map. Many concurrent requests can queue large buffers while one worker processes them. The document states that worker OOM terminates the endpoint process.
Add a per-fork concurrency limit and bounded queue before buffering request bodies. Reject excess work with explicit backpressure, such as 429 or 503. Test concurrent requests at the metadata-size limit.
