Subject [jira] Commented: (CASSANDRA-1607) Deprecate ConsistencyLevel.ZERO
Date Mon, 11 Oct 2010 22:43:33 GMT


Brandon Williams commented on CASSANDRA-1607:

To clarify, I mean take CL.ZERO out back and shoot it in the head, not deprecate it.  Remove
it completely.

> I've never heard of a valid use case for CL.ZERO, but I've seen countless people run
OOM from using it.  Each time, I tell them to use ONE instead and they do, clearly because
they don't know why they chose ZERO to begin with.  If someone does figure out a use case
for this in the future, they can describe_ring, hash the key themselves to find the correct
node, and use CL.ONE with the commit log in periodic mode.
