Re: Github pull requests
I think it would certainly make contributing to Cassandra more straightforward. I'm not a committer, so I don't regularly create patches, and every time I do I have to search/verify that I'm doing it right. But pull requests? I make pull requests every day, and GitHub makes that process work the same everywhere.

Re: Cassandra 2.0 with Hadoop 2.x?
Clint, I'm hoping that https://issues.apache.org/jira/browse/CASSANDRA-5201 will make it into Cassandra 2.0, as it is a general purpose solution that will work for both mapred, and mapreduce based code.

Re: maximum sstable size
It's possible, take a look at the CompactionTask class for some guidance on what we did for LCS.

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. -- Ben Coverston DataStax -- The Apache Cassandra Company
