Subject [jira] [Commented] (CASSANDRA-7056) Add RAMP transactions
Date Mon, 28 Jul 2014 15:23:42 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-7056?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14076297#comment-14076297
] 

Jonathan Ellis commented on CASSANDRA-7056:
-------------------------------------------

bq. I'd also vote for making UNLOGGED the default (implicit) BATCH behavior, now that the
LOGGED batches would cost even more than they do now.

UNLOGGED is still a misfeature, so I don't see how the cost of RAMP affects our choice of
default.  (And for the record I think RAMP should definitely be the default; it matches users'
assumptions so much better.)

I guess we could add UN_ISOLATED to request logged-without-ramp though.

> We should take a look at [RAMP|http://www.bailis.org/blog/scalable-atomic-visibility-with-ramp-transactions/]
transactions, and figure out if they can be used to provide more efficient LWT (or LWT-like)
operations.
