I don’t know maybe my problem is normal behavior of MongoDB but I need to find a solution for that. So, I am using 3 node replicaset with 1 primary, 1 secondary and 1 arbiter. My servers are powerfull and can handle 3K ops . When secondary is down for a reason, MongoDB slows down significant like from 3000 ops to 50 ops. As I said that may be normal behavior.
I need to solve this slowness when a node is down.
- I can not remove down node and re-add it when become online because data is big, i can not wait to re-sync.
- when I lost a node, I restore it from backup and open it. It catches from primary in a minute.
MongoDB version is 4.2.4. do you have any suggestion about my problem? Thank you!
