Subject [jira] [Commented] (CASSANDRA-2280) Request specific column families using StreamIn
Date Wed, 23 Mar 2011 18:54:05 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2280?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13010287#comment-13010287
] 

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

I'd prefer to avoid special-casing empty list and just pass all CF names when that is what
we want.  A constructor or factory method that does not take a columnFamilies parameter could
default to that, too.  (This is easy w/ CFS.all, but that would require using CFS objects
instead of Strings. Which may be better anyway but it is hard to tell w/o trying it.)

Nit: we usually use "cfs" to abbreviate ColumnFamilyStore, suggest expanding to columnFamilies.

> 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.
