[ReverseIndexCache Location](https://github.com/apache/gravitino/blob/main/core/src/main/java/org/apache/gravitino/cache/ReverseIndexCache.java) Based on the above implementation, `ReverseIndexCache` that is used in the `CaffeineEntityCache`, it uses a plain `HashMap` backed by `HashSet` collections for values. While this works for simple lookups, the structure is not inherently thread-safe and may result in race conditions under concurrent access. Additionally, per-element updates like `addAll` loop through values individually, which becomes costly for large tag sets. To improve, replacing the backing structures with concurrent collections and supporting batched or delta updates would reduce contention and improve scalability. -- This is an automated message from the Apache Git Service.
