Thanks for the answer. I've tested it by myself now, and indeed it works. Only note I have is that you have to run "nodetool upgradesstables -a", so all sstables are updated. Katriel On Tue, Apr 29, 2014 at 12:22 PM, Alain RODRIGUEZ wrote: > Hi, I would say: > > 1 - Yes > 2 - Yes (No major com

Hi, I would say: 1 - Yes 2 - Yes (No major compaction needed, upgradesstables should do the job) As always in case of doubt, as always, test it. ìn this case you can even do it using a local machine. Alain 2014-04-29 9:57 GMT+02:00 Katriel Traum : > Hello, > > I am running mostly Cassandra 1.

Migrating from Snappy to LZ4 on C* 1.2

2014-04-29 Thread Katriel Traum
Hello, 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?
