This release marks the conversion of our first JavaScript-based REST API to Java. The /api/v1/network/stake was rewritten in the rest-java module, but it's currently disabled by default as we roll it out according to the plan. Conversion of our code base to a single language will improve code reuse and reduce bugs. During our testing, we were pleasantly surprised that it also improved performance. The /api/v1/network/stake API more than doubled in requests per second as a result of the conversion.
It's exciting to see multiple outside contributions come in from community members! @pratibhanaikk worked on removing our dependency on Spring Cloud. Meanwhile @HamzaElzarw-2022 removed our use of the @Lazy annotation. Both of these streamline our application and make progress towards our goal of native compilation.
HIP-1127 Unified transaction record format was integrated into our block node code. Additional integration test coverage for block nodes was implemented to ensure single and multiple nodes work properly.
Finally, an entity relationship diagram was added to aid operators and developers in understanding the structure of the database schema. The ERD diagram is in draw.io format and can be uploaded and viewed directly on that site.
Breaking Changes
With the removal of Spring Cloud, the automatic configuration refresh from Kubernetes ConfigMaps and Secrets named after the spring.application.name property will no longer work. If you're an operator that depends upon this functionality, you'll need to migrate to manually specifying the configuration volumes to mount.
