Re: Best practices while designing backup storage system for big Cassandra cluster

Another approach to avoiding the full backup I/O hit would be to rotate a node or small subset of nodes that do full backups routinely, so that over the course of a month or two you get full backups. Of course this assumes you have incremental ability for the other backup days/dates. On Mon, Apr 1

Re: Multi-DC replication and hinted handoff

Hi Jens, I am reading Cassandra The definitive guide and there is a chapter 9 - Reading and Writing Data and section The Cassandra Write Path and this sentence in it: If a replica does not respond within the timeout, it is presumed to be down and a hint is stored for the write. So your node migh
