Hi All,

I have an eks cluster on which i am running spark operator and hazelcast installed via helm.

My Spark job conects to a RDS database and loads the data into the hazelcast cache. Now all of this works fine when i have a single pod of hazelcast and the the data loading happens within seconds.

However when i increase the member count of hazelcast to 2 or more ...it loads the data very slowly into cache and it takes few hours to load the data which only takes few seconds on single member.
