Subject Re: How to add a node with zero downtime
Date Tue, 21 Mar 2017 18:38:43 GMT
Possible areas to check:
- too few nodes (node overload) - you did not indicate either replication
factor, number of nodes. Assume nodes are *rather* full.
- network overload (check your TORS's errors, also the tcp stats on the
relevant nodes)
- look for stop the world garbage collection on multiple nodes.
