CCR has some limitation around replication of some of the kibana indexes I believe, or is this an incorrect statement?
I’m looking to make this highly available across data centers without having to create additional functionality to failover kibana and all the production data that is not being replicated with CCR. I want a failure to be zero touch.
The other issue is that with a hot standby, I’m just wasting compute sitting there when I could be using it.
I’ve been doing some testing with by pushing about 50k eps on primary shards with around 30ms latency between sites (i purposely picked 30ms to see how sensitive to latency it was). It appeared on the surface to eat that up fairly well. No cluster issues at all. Of course I understand that there is going to be a reduced performance, but how bad is it?
If I said that this cluster is not ingesting anything but local system indices and is just focusing on CCS, is spanning this across two DC’s that bad of an idea?
