1.2.6

[matiwinnetou]

Highlights 🔦

• Hardware Profiles: introduced entry_level and mid_level hardware profiles / configurations to ease scaling software and best tune software towards certain physical / virtual hardware specs
• Bug Fixes: addressed a couple of stability and correctness issues across the system.
• Cardano Node Upgrade: bumped to version 10.1.4 for compatibility and performance improvements.
• Scalability Testing Framework: Initial version to create, evaluate, and tune additional hardware profiles
• Rosetta documentation: initial version of new rosetta documentation https://cardano-foundation.github.io/cardano-rosetta-java/ with ability to invoke Rosetta endpoints
• Small Performance / Scalability Tweaks: connection pooling for Http connections (HTTP2) on api to yaci-indexer communication, using structured concurrency for better resilience against resource starvation issues
• Testing: added more unit tests / regression and flow tests

Breaking changes ⚠️

• you are now required to specify hardware profile upon starting cardano rosetta platform / stack.
  e.g. example for "mid_level" profile:

docker-compose --env-file .env.docker-compose --env-file .env.docker-compose-profile-mid-level -f docker-compose.yaml up -d

List of hardware profile names can be access at: https://github.com/cardano-foundation/cardano-rosetta-java/wiki/9.-Hardware-Profiles, we will be adding more profiles in futher versions, it is an elementary list to get started.

Known issues ⚠️

• our scalability shows a slightly worse scalability numbers for mid_level hardware profile for "a single docker image" deployment option contrary to a "docker compose" way of running a project, the exact numbers will be published soon on our documentation pages: https://cardano-foundation.github.io/cardano-rosetta-java/
