Paul Banks 0b5a078b95 Optimize health watching to single chan/goroutine. (#5449 ) Refs #4984. Watching chans for every node we touch in a health query is wasteful. In #4984 it shows that if there are more than 682 service instances we always fallback to watching all services which kills performance. We already have a record in MemDB that is reliably update whenever the service health result should change thanks to per-service watch indexes. So in general, provided there is at least one service instances and we actually have a service index for it (we always do now) we only ever need to watch a single channel. This saves us from ever falling back to the general index and causing the performance cliff in #4984, but it also means fewer goroutines and work done for every blocking health query. It also saves some allocations made during the query because we no longer have to populate a WatchSet with 3 chans per service instance which saves the internal map allocation. This passes all state store tests except the one that explicitly checked for the fallback behaviour we've now optimized away and in general seems safe.		6 years ago
