[VOTE] Release Apache Cassandra 1.1.0-beta2

2012-03-23 Thread Sylvain Lebresne
There is has been quite some changes since the beta1[1] (including some non
trivial ones) and so while we still have a few outstanding small issues that
may need to be addressed before calling for a release candidate, a new beta
seems like the reasonable thing to do. I thus propose the following artifacts
for release as 1.1.0-beta2.

sha1: 643d18af24574d82ba565f6fe6482225f89f5d18
Git: 
http://git-wip-us.apache.org/repos/asf?p=cassandra.git;a=shortlog;h=refs/tags/1.1.0-beta2-tentative
Artifacts: 
https://repository.apache.org/content/repositories/orgapachecassandra-104/org/apache/cassandra/apache-cassandra/1.1.0-beta2/
Staging repository:
https://repository.apache.org/content/repositories/orgapachecassandra-104/

The artifacts as well as the debian package are also available here:
http://people.apache.org/~slebresne/

The vote will be open for 72 hours (longer if needed).

No I don't think you did, in fact, depending on the size of your SSTable a
contiguous range (or the entire SSTable) may or may not be affected by a
cleanup/move or any type of topology change. There is lots of room for
optimization here. After loading the indexes we actually know start/end
range for an SSTable so we can include/exclude it in any such operation.

Just note that unless there is some correlation between range and
these sstables being created to begin with (like with leveled), you're
highly unlikely to be able to optimize here. For uniformly distributed
tokens (hashed keys), all sstables are likely to have almost the
entire possible token range in them.

As Peter pointed out, for random partitioner, the rows of  a specific range
might scatter around all sstables.

Unless whole sstable can be ignored, disk seek is the performance killer
here.
