Subject Migrating from Snappy to LZ4 on C* 1.2
Date Tue, 29 Apr 2014 07:57:04 GMT

I am running mostly Cassandra 1.2 on my clusters, and wanted to migrate my
current Snappy compressed CF's to LZ4.

Changing the schema is easy, my questions are:
1. Will previous, Snappy compressed tables still be readable?
2. Will upgradesstables convert my current CFs from Snappy to LZ4? Or do I
have to run major compaction?
