Subject [jira] [Commented] (CASSANDRA-2280) Request specific column families using StreamIn
Date Fri, 08 Apr 2011 20:41:05 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2280?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13017634#comment-13017634
] 

Jonathan Ellis commented on CASSANDRA-2280:
-------------------------------------------

bq. otherwise we'd have to perform a lookup during deserialization to build the list for localhost

Right. That's a cleaner approach, since the semantics of what a columnFamilies list is doesn't
have to be special cased outside the deserialize, which is the right place to deal with this.

Speaking of which, don't we need some code in StreamOutSession.create to force the cF list
to all, if target is an old-version node?  Otherwise what we send, will not be what target
expects.

> StreamIn.requestRanges only specifies a keyspace, meaning that requesting a range will
request it for all column families: if you have a large number of CFs, this can cause quite
a headache.
