Read-repair working, repair not working?

2013-02-10 Thread Brian Fleming
** Hi, ** ** I have a 20 node cluster running v1.0.7 split between 5 data centres, each with an RF of 2, containing a ~1TB unique dataset/~10TB of total data. ** ** I’ve had some intermittent issues with a new data centre (3 nodes, RF=2) I brought online late last year with data cons

Efficiency of Cross Data Center Replication...?

2011-11-16 Thread Brian Fleming
Hi All, I have a question about inter-data centre replication : if you have 2 Data Centers, each with a local RF of 2 (i.e. total RF of 4) and write to a node in DC1, how efficient is the replication to DC2 - i.e. is that data : - replicated over to a single node in DC2 once and internally replic
