Hello, we have several pods with ignite caches running in kubernetes. We only 
use memory mode (not persistence) and want to perform rolling update of without 
losing data. What metric should we monitor to know when it’s safe to replace 
the next pod?

We have tried the Cluser.Rebalanced (1) metric from JMX in a readiness probe 
but we still end up losing data from the caches. 

1) https://ignite.apache.org/docs/latest/monitoring-metrics/new-metrics#cluster

Should we use another mechanism or metric for determining the readiness of the 
new started pod?
