    [ https://issues.apache.org/jira/browse/CASSANDRA-2475?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13169644#comment-13169644

Eric Evans commented on CASSANDRA-2475:
---------------------------------------

OK, the attached v2-* patches are:

* v2-0001-CASSANDRA-2475-rickshaw-2475-v3.1.patch.txt
* v2-0002-rickshaw-2475-v3.2-Thrift.patch-w-changes.txt

Rick's last, rebased against trunk as of today.

* 0003-eevans-increment-thrift-version-by-1-not-3.txt

Increment Thrift minor from 19 to 20, instead of 22

* 0004-eevans-misc-cleanups.txt

Various code cleanups

* 0005-eevans-refactor-for-better-encapsulation-of-prepare.txt

A refactoring of {{CassandraServer.prepare_cql_query}} and {{QueryProcessor.prepare()}} to
encapsulate query preparation within {{QueryProcessor}} 

* 0006-eevans-log-queries-at-TRACE.txt

Log queries at TRACE.

* 0007-use-an-LRU-map-for-storage-of-prepared-statements.txt

Turn the Map that stores prepared statements into an LRU cache (currently evicts when size()
> 50)

----

Patches 3-6 are pretty minor and I would have just committed them as-is, but it wouldn't hurt
to have someone (Rick?) else look at 7 (at least).
