T Jake Luciani commented on CASSANDRA-2683:
-------------------------------------------
bq. I'd rather just && the bypass values together and if any CF wants the CL,
we throw the whole RM into it
that would make the CL logic non-deterministic since the flag would be
respected depending on what gets sent with it...
I was going to group the non-cl vs cl applies together but that would require
another container copy. My patch tries to make the check as low impact as
possible...

> Some data in cassandra does not need durability on a single node. Also ec2
> users often wish to disable the commitlog since they are using the ephemeral
> disks.
> This patch let's you set bypass_commitlog=true in the CfMetaData, the effect
> being RowMutations on ColumnFamilies with this flag will bypass the commit log
