Hi, This week - Worked out, fixed and documented some bugs in the Snappy service. My initial conclusion needed some fine-tuning, it might be possible to make RocksDB work with our modifications, if we are able to switch the default compression engine on startup. I also fixed the crash on startup for the Snappy service. - Implemented a solution to conditionally include the custom headers only for the relevant storage engines. This will also allow us to skip over a storage engine (for example RocksDB) if it does not work well with our modifications. # in cmake/plugin.cmake IF( plugin STREQUAL "CONNECT" OR plugin STREQUAL "INNOBASE" OR plugin STREQUAL "MROONGA" OR plugin STREQUAL "ROCKSDB" ) INCLUDE_DIRECTORIES(${CMAKE_SOURCE_DIR}/include/compression) ENDIF() - Reverted the implementation for the Snappy and LZO service. - Rebased the branches onto the latest 10.5 branch. Next week - Implement the BZip2 service. - Work on the ZStd and Snappy service to try and make it work with RocksDB. - Continue writing the HOWTO file. Thanks, Kartik ​
