Currently we use the custom lz4-block scheme when compressing data. This scheme automatically calculates and write a checksum when compressing. We do not actually read this checksum when decompressing so it is unnecessary. This commit resolves this by not writing a no-op checksum. This will break arbitrary decompressors. However, since the lz4 block format is not an official format anyway, this should be fine. Relates to elastic#73497/

There was a problem hiding this comment.
LGTM.
Depending on benchmarks we may want this in 7.15 too.
