[I] cluster: cache consistent hash when healthy endpoint set is unchanged [dubbo-go-pixiu]
mochengqian opened a new issue, #942:
URL: https://github.com/apache/dubbo-go-pixiu/issues/942
PR #932 rebuilds the consistent hash view from the healthy endpoint set during snapshot publication and lazy access. Maglev and ring-hash paths can still pay unnecessary rebuild cost when runtime health or membership updates publish a successor snapshot whose healthy set is effectively unchanged.
Proposed:
- Track enough snapshot identity to reuse the previous consistent hash when the healthy endpoint set and hash config are unchanged.
- Extend benchmarks to cover health flaps and membership churn for ring-hash and Maglev clusters.
- Keep correctness first: never reuse a hash across endpoint identity, address, or hash config changes.
Reference: listed as a known follow-up in PR #932.
