Subject heads up on on-disk data format changes in trunk
Date Tue, 04 Aug 2009 22:52:59 GMT
Hi guys,

We're trying to get the data format incompatibilities done with before
we put out a 0.4 beta.  There's 3 coming up.  In order of when they
are likely to be finished:

https://issues.apache.org/jira/browse/CASSANDRA-341 -- to fix bugs (today)
https://issues.apache.org/jira/browse/CASSANDRA-332 -- to make our
indexing more awesome (tomorrow?)
https://issues.apache.org/jira/browse/CASSANDRA-233 -- to make small
rows less bloated (by the end of the week)

For 341 and 332 forcing a compaction of your old sstables should cause
new sstables to be written in the correct format.  (Compaction ignores
the old indexes and creates new ones.)

For 233 there is no easy way to convert old sstables.

-Jonathan
