Automated Repair on multiple nodes

2013-08-02 Thread Mohit Anchlia
We currently run automated repairs sequentially on all the nodes. However, as we grow the cluster we now need to run repair on multiple nodes in parallel to be able to finish it withing gcgrace seconds.

If you have time, this will show you how counters internally work : http://blip.tv/datastax/counters-in-cassandra-5497678 (video from Sylvain @CassandraSF2011) If you just want to know what is possible to do or not with counters but not necessary why, better read this http://www.datastax.com/dev/b
