Kein Problem :)
Actually you could even use the slave cluster for writes (those changes would not get replicated back, though). The timestamping of HBase makes that all possible and easy. I am working on Master-Master replication (see HBASE-2195). -- Lars ________________________________ From: Jens Hartung <[email protected]> To: [email protected] Sent: Wednesday, September 7, 2011 1:01 PM Subject: Re: Question about HBase Cluster Replication Hallo Lars, thanks for your response. I had a discussion with my tutor about the cluster-replication feature. He thought, this is only for backup purposes. And I didn't find the decisive hint, that the slave can be used for read-only queries.
