Hi all,



Has anyone tried running a test against Redis configured in AWS MemoryDB Redis instance? When I run a load/single-user test I get interim connection issues and it kills the thread.



In the logs, I see below:

I have given the cluster URL for AWS MemoryDB Redis instance in the script. Redis cluster has implemented a slot migration not sure if it is coming into play here and how to handle that in the script, any thoughts?
Is there a way to give Redis startup_nodes in the script instead of cluster URLs to avoid AWS Redis Cluster - MOVE error?

Please suggest
Joe
