I remembered that on the 1.2 branch, even though the auto_snapshot param was set to false, truncating leads to snapshot creation that forced us to manually remove the snapshot folder on disk
Both DROP and TRUNCATE auto_snapshot by default, yes. > Can you please explain what problems DROP/CREATE keyspace may cause? Check JIRA, but in general currently DROP/CREATE same entity can cause bugs. DROP/CREATE with always unique names should be fine. > Seems like truncate working per column family and I have up to 10.

CL=ANY is a problem with consistency. Wherever you read the instruction to consider ever using it for any reason, strongly consider never visiting that site again. RF=2 means you can't use QUORUM without using CL.ALL. Not being able to use QUORUM can result in consistency problems. Using CL.ALL results in availability problems. =Rob
