We just found out that Jonathan Ellis, project chair for Apache Cassandra and co-founder of DataStax, will be in the Bay Area on April 23. We have invited him to speak on Cassandra 1.1 -- which has just been released.
Apache Cassandra 1.1 includes several significant new features, like live traffic sampling, row level isolation, and full support for CQL. If you haven't looked at Cassandra in a while, or are just now starting to check it out, this is a great opportunity to find out where it is now, and where it's going.
