Hello We have a 3 Solr Servers replication schema, one Master and 2 Slaves, commits are done every 5 minutes on the Master and an optimize is done once a day during midnight, snapshots are copied via rsync to Slaves are done every 10 minutes, we are facing serious problems when doing the sync after the optimize and keeping Slaves serving queries as usual, active connections to Slaves increase highly during Optimize Snapshot sync, is there any way we can tune this process ? we try this process :
1. stopping Sync process on one Slave 2. taking the other one out of the LB pool 3. do the sync on this offline Slave 4. after sync is over add back to LB Pool synced Slave 5. take other Slave out from LB Pool 6. start sync process on the offline Slave 8 add back synced Slave to LB Pool following these steps we sometimes face high active connections when moving Slaves back to LB Pool. Has anybody faced this situation in production envs ? Thanks Pablo
