* | Optimise queueing of inbound replication commands (#7861) | Richard van der Hoff | 2020-07-16 | 1 | -0/+1 |
When we get behind on replication, we tend to stack up background processes behind a linearizer. Bg processes are heavy (particularly with respect to prometheus metrics) and linearizers aren't terribly efficient once the queue gets long either. A better approach is to maintain a queue of requests to be processed, and nominate a single process to work its way through the queue. Fixes: #7444 |
