Subject [jira] [Commented] (CASSANDRA-9283) Deprecate unlogged batches
Date Mon, 04 May 2015 20:58:07 GMT


Aleksey Yeschenko commented on CASSANDRA-9283:

COUNTER mutations already avoid batchlog. This doesn't really change anything wrt CASSANDRA-7351.

Question is, whether or not we should drop COUNTER and UNLOGGED *syntax* and only leave BEGIN
BATCH syntax available for everything.

But that's not a question for today. Today we should just formally note in the spec that this
stuff is deprecated, and emit warning on the server side.

> Note that the main "good" use case for unlogged batches, of multiple updates in a single
partition key, is "free" when done as a logged batch.  So really unlogged batches mainly serve
as a honeypot to trick new users into abusing them in misguided bulk loading attempts.
