Hi All, After releasing Amdatu Big Data RC3 (formerly known as Amdatu Cassandra), a performance issue was found with respect to the Cassandra Persistence Manager, causing excessive garbage allocations. This issue has been in there for a long time (at least since Amdatu 1.1). A quick performance test proved that most methods in the Cassandra Persistence Manager can be improved with a factor 2 till 10 with a simple fix. Because of this major performance improvement, it was decided to include this patch into 0.2.1 and so a new release candidate was created. The improvement that has been applied in RC3 is:
http://jira.amdatu.org/jira/browse/AMDATUCASSANDRA-132 Excessive garbage allocation in getSuperRow method All information, including download links, can be found on this WIKI page: http://www.amdatu.org/confluence/display/Amdatu/AC+-+Releases Again, there are no unclosed issues for 0.2.1, so it's time for another vote for the release of Amdatu Cassandra 0.2.1. The vote will be closed on Friday, November 18, at 17:00. If there are no binding -1 votes, 0.2.1 will be released on Monday, November 21.
