…ngester, store-gateway and compactor. These are values which help reduce the pressure on a KV store or reduce the CPU spent by memberlist in passing messages. The tradeoff is that abrupt shutdowns/crashes of components will take longer to detect by peers. We've been running with these values at Grafana Labs for some time and haven't seen problems.

thanks for driving this to completion @pracucci. In principle LGTM. Reviewing this code raises questions that I didn't ask myself before 😅

I took ownership of this PR from Dimitar. I did the changes on Dimitar's PR, so I've asked Dimitar to review it. Dimitar approved, but can't officially approve its own PR, so I'm approving it (but it's not a self-approval, it's Dimitar approving it in practice).

In this PR we're upstreaming a config change we've done long time ago at Grafana Labs, relaxing the hash ring heartbeat period and timeout for distributor, ingester, store-gateway and compactor.
These are values which help reduce the pressure on a KV store or reduce the CPU spent by memberlist in passing messages.The tradeoff is that abrupt shutdowns/crashes of components will take longer to detect by peers. We've been running with these values at Grafana Labs for some time and haven't seen problems.
