Since this update follows the default compression level and current buffer size if they are not set, there is no backward compatibility problem.

Further works

Alongside the compression level, I am trying additional configuration options, like the following:

Compression buffer size option

...

At the initial stage, I considered the compression buffer size option was also under consideration. However, during the benchmark, I could not find any its positive impacts on produce speed nor or compressed size. So it was rejected. I am still investigating whether it can improve the disk write speed, e.g., Broker-size recompression or compaction.

Long window size with Zstandard

With 1.3.2, Zstandard introduced compression/decompression with long window size. This option can improve the compression/decompression speed for some levels.
