Re: what happends with slave during repliacation?
Hi Amanda, we don't use solr cloud jet, just 3 dedicated server. When it comes to distribution the choice will be either solr cloud or elastic search. But currently we use unix shell scripts with ssh for switching. Easy, simple, stable :-) Regards, Bernd Am 21.09.2012 16:03, schrieb yangqian_nj: Hi Bernd, You mentioned: Only one slave is online the other is for backup. The backup gets replicated first. After that the servers will be switched and the online becomes backup. Do you please let us know how to do you do the Switch? We use SWAP to switch in solr cloud. After SWAP, when we query, from the tomcat log, we could see the query actually go to both cores for some reason.

what happends with slave during repliacation?
Hi All! I want to replicate my Solr server. At the begining I want to have one master and one slave. Master would serve for indexing and slave (slaves in the future) would be used for searching. I was wondering if anybody could tell me what happens with slave during replication. Is it unavailable? Could it serve searches? What happens if it has to replicate huge amount of data? Regards, Alex
RE: what happends with slave during repliacation?
Hi Alex, During replication also your slave will be available for searches and opens a new searcher just after replication. You won't get any downtime, but you might not have warmed cache at the moment. Please look into cache configuration for solr.

Re: what happends with slave during repliacation?
Hi Alex, during replication the slave is still available and serving requests but as you can imagine the responses will be slower because of disk usage, even with 15k rpm disks. We have one master and two slaves. Master only for indexing, slaves for searching. Only one slave is online the other is for backup. The backup gets replicated first. After that the servers will be switched and the online becomes backup. Regards Bernd Am 20.09.2012 09:39, schrieb Alex: Hi All! I want to replicate my Solr server.
