nope!

Memory is maybe 50% full. We are totally over provisioned. We actually just downsized and it didn’t impact anything.

We do expire but we don’t think we have a thundering herd problem with them all happening at the same time.

Running from the client side says that the config command doesn’t exist. Not sure how to run from the server side on elasticache.

We also pool our clients heavily. Maybe we could reduce the new connections to zero to test.

Hmm. We have super low CPU utilization- something like 9%. This is also across 10+ different clusters.

My understanding is elasticache does not let you turn them off.

Has anyone seen max (p100) client latencies of 300 to 400ms but totally normal p99? We see this across almost all our redis clusters on elasticache and have no idea why. CPU usage is tiny. Slowlog shows nothing.

this is a huge issue for us and I'm extremely unhappy this was not clear in the docs

Oh wow that's awesome. Thanks! Will send an email.
