James Oliver commented on KAFKA-1493:
-------------------------------------
Jun,
My pleasure. The TODOs are parts of the specification that are unimplemented,
but are not required. I left them in there as hints if/when the spec is
contributed back to lz4-java. The validation routines will disallow the use of
any portion of the spec that is unimplemented, but it's totally usable.
What the spec can do - compress & decompress messages using 64kb/256kb/1mb/4mb
blockSize (64kb by default) with optional block checksums (disabled by default)
What the spec cannot do - decompress messages compressed by an implementation
supporting some of the missing features. If this were to occur, a
RuntimeException with detailed information will be thrown.
> Use a well-documented LZ4 compression format and remove redundant LZ4HC option
