What changes were proposed in this pull request?
Adds a design doc,
design-docs/entity-cache-multinode-changelog-design.md, proposing how to make the entity store cache (gravitino.cache.enabled) usable in multi-node deployments by invalidating it across nodes via the existingentity_change_logandEntityChangeLogPoller. It presents two options (coarse by-metalake vs. precise per-endpoint) with a recommendation, plus a consistency model and a coverage audit.Why are the changes needed?
Today the entity store cache only invalidates locally, so multi-node deployments must disable it, which hurts performance (Iceberg especially). This is design-only; no code behavior changes yet.
Fix: #11737
Does this PR introduce any user-facing change?
No. Documentation and design only.
How was this patch tested?
No code changes; not applicable. The doc passes the repo docs-style audit scripts.
