HI ; Your objective is add the Keyspace 2 to cluster 1. The documentation link being referred to is to add a new datacenter [not applicable to you].
You need to : a. take a snapshot of keyspace 2 on cluster2 b. use sstable loader to copy the keyspace2 onto cluster 1 c. run a 'nodetool repair' on cluster 1 d. de-commission cluster2. You are ready to use cluster 1 [with both keyspaces within it] Hope this helps Jan -------------------------------------------- On Thu, 4/21/16, Arlington Albertson <arlingtonalbert...@gmail.com> wrote: Subject: Combining two clusters/keyspaces into single cluster To: user@cassandra.apache.org Date: Thursday, April 21, 2016, 6:15 PM Hey Folks, I've been looking through various documentations, but I'm either overlooking something obvious or not wording it correctly, but the gist of my problem is this: I have two cassandra clusters, with two separate keyspaces on EC2. We'll call them as follows: cluster1 (DC name, cluster name, etc...)keyspace1 (only exists on cluster1) cluster2 (DC name, cluster name, etc...)keyspace2 (only exists on cluster2) I need to perform the following:- take keyspace2, and add it to cluster1 so that all nodes can serve the traffic- needs to happen "live" so that I can repoint new instances to the cluster1 endpoints and they'll just start working, and no longer directly use cluster2- eventually, tear down cluster2 (easy with a `nodetool decommission` after verifying all seeds have been changed, etc...) This doc seems to be the closest I've found thus far:https://docs.datastax.com/en/cassandra/2.1/cassandra/operations/ops_add_dc_to_cluster_t.html Is that the appropriate guide for this and I'm just over thinking it? Or is there something else I should be looking at? Also, this is DSC C* 2.1.13. TIA! -AA
