Re: Streaming from 1 node only when adding a new DC

For rebuild, replace and -Dcassandra.consistent.rangemovement=false in general we currently pick the closest replica (as indicated by the Snitch) which has the range, what will often map to the same node due to the dynamic snitch, specially when N=RF. This is good for picking a node in the same DC

We've tested with C* 2.1.14 version Yes VNodes with 256 tokens Once all the nodes in dc2 are added, schema is modified to have RF=3 in dc1 and RF=3 in dc2. Then on each nodes of dc2: nodetool rebuild dc1 Le 14 juin 2016 10:39, "kurt Greaves" a écrit : > What version of

What version of Cassandra are you using? Also what command are you using to run the rebuilds? Are you using vnodes? On 13 June 2016 at 09:01, Fabien Rousseau wrote: > Hello, > > We've tested adding a new DC from an existing DC having 3 nodes and RF=3 > (ie all nodes have

Streaming from 1 node only when adding a new DC

Hello, We've tested adding a new DC from an existing DC having 3 nodes and RF=3 (ie all nodes have all data). During the rebuild process, only one node of the first DC streamed data to the 3 nodes of the second DC. Our goal is to minimise the time it takes to rebuild a DC and would like to be
