My understanding is Thrift is being removed from Cassandra in 4.0, but will COMPACT STORAGE be removed as well? Clearly the two are related, but COMPACT STORAGE had a performance advantage in addition to Thrift compatibility, so its status is ambiguous.
I recall vague chatter, but no explicit deprecation notice or 4.0 plan for removal of COMPACT STORAGE. Actually, I don't even see a deprecation notice for Thrift itself in CHANGES.txt. Will a table with only a single non-PK column automatically be implemented at a comparable level of efficiency compared to the old/current Compact STORAGE? That will still leave the question of how to migrate a non-Thrift COMPACT STORAGE table (i.e., used for performance by a CQL-oriented developer rather than Thrift compatibility per se) to pure CQL. -- Jack Krupansky
