Subject [jira] [Commented] (CASSANDRA-5038) LZ4Compressor
Date Thu, 06 Dec 2012 22:36:35 GMT


T Jake Luciani commented on CASSANDRA-5038:

Hi Adrian,

Cool,  yeah I'm not sure if we can use the "known size" decompressor, does it have to be exact
or can it be upper bounded? We know from the block size the max compressed length.

Thanks for the work and good point about also looking for JNI.  I'd suggest you add a simple
way for us to pick the best compressor for our node.
