Subject [jira] [Commented] (CASSANDRA-5887) add lz4 compression for internode compressio
Date Thu, 15 Aug 2013 02:10:49 GMT


Jonathan Ellis commented on CASSANDRA-5887:

We could omit the option if we make LZ4 only a fallback if Snappy isn't present, but it probably
makes more sense to make LZ4 the new default for the same reasons we switched to it for sstable
compression, in which case we do want an option so existing clusters aren't screwed as soon
as a new node restarts.

 If Snappy is not available this will fail.  lz4 compression is vetted for use in Cassandra.
 Would it make sense to use lz4 for internode compression ?  Would a new config setting internode_compressor
be needed for compatibility ?
