aiborodin opened a new pull request, #13382: URL: https://github.com/apache/iceberg/pull/13382
We recently discovered that [LRUCache](https://github.com/aiborodin/iceberg/blob/compare-caffeine-cache-perf-with-linked-map/flink/v2.0/flink/src/jmh/java/org/apache/iceberg/flink/sink/dynamic/LRUCache.java), based on `LinkedHashMap`, has a throughput almost two times as high as the Caffeine Cache with the maximum size configured. Please, see JMH benchmark results [here](https://github.com/aiborodin/iceberg/blob/compare-caffeine-cache-perf-with-linked-map/flink/v2.0/flink/src/jmh/java/org/apache/iceberg/flink/sink/dynamic/CacheBenchmark.java#L43). Let's use `LRUCache` in `TableMetadataCache` to improve the cache performance of the `DynamicIcebergSink`. -- This is an automated message from the Apache Git Service.
