Aliaksandr Valialkin a1629bd3be lib/netutil.ConnPool: skip dialing remote address if the previous dial attempt was unsuccessful ... If the previous dial attempt was unsuccessful, then all the new dial attempts are skipped until the background goroutine determines that the given address can be successfully dialed. This reduces query latency when some of vmstorage nodes are unavailable and dialing them is slow. This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/711 This commit is based on ideas from the https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2756 The main differences are: - The check for healthy/unhealthy storage nodes is moved one level lower from app/vmselect/netstorage to lib/netutil.ConnPool. This makes possible re-using this feature everywhere lib/netutil.ConnPool is used. - The check doesn't take into account handshake errors for already established connections. Handshake errors usually mean improperly configured VictoriaMetrics cluster, so they shouldn't be ignored.		2022-06-20 17:33:54 +03:00
