Summary: Right now, in Java's Get() calls, the way Get() is treated is inefficient. Status.NotFound is turned into an exception in the JNI layer, and is caught in the same function to turn into not found return. This causes significant overhead in the scenario where most of the queries ending up with not found. For example, in Spark's deduplication query, this exception creation overhead is higher than Get() itself. With the proposed change, if return status is NotFound, we directly return, rather than going through the exception path Pull Request resolved: https://github.com/facebook/rocksdb/pull/14095 Test Plan: Existing tests should cover all Get() cases, and they are passing.
