Cassandra take a snapshot after a column family update

2011-03-30 Thread Roberto Bentivoglio
Hi all, I've executed from cassandra-cli on a production server (0.7.0) the following instruction: update column family CFName with gc_grace=0; I'm really surprise that Cassandra take a snapshots of the data for every update that I executed. Is this a normal behaviour? Thanks, Roberto

AFAIK snapshots are taken for drop CF, drop KS and truncate CF also during compaction if enabled via yaml. Cannot see anything in the code for 0.7 to snapshot during CF update. What was the name of the snapshot folder ? btw it's a really good idea to upgrade to 0.7.4 if possible Aaron On 30
