Description:
Previous benchmarks demonstrated that the default
zstdcompression works exceptionally well for Hiero block data (e.g. see #749 ). This PR productionalizes theZstdGrpcTransformerby moving it from integration tests to a newpbj-grpc-commonmodule and making both the GRPC client and server code register the transformer in theirstatic{}sections. This allows us to have a dependency on thecom.github.luben:zstd-jnionly once, and additionally, we don't make the lightweight and genericpbj-runtimemodule depend on it. Only clients that use PBJ GRPC will get this new dependency and will support thezstdcompression automatically, which can be enabled via the corresponding PbjGrpcClient/ServerConfig objects.Related issue(s):
Fixes #766
Notes for reviewer:
A new unit test is added for the transformer.
