Summary: Fixes https://github.com/facebook/rocksdb/issues/7430 Change ParseInternalKey() to return Status instead of bool. db_bench (seekrandom) based before/after results with value size of 100 bytes and 16 bytes can be found at (tests ran on an udb server): https://www.dropbox.com/s/47bwamdy5ozngph/PIK_ret_Status_results.xlsx?dl=0  Pull Request resolved: https://github.com/facebook/rocksdb/pull/7457 Reviewed By: ajkr Differential Revision: D24002433 Pulled By: ramvadiv fbshipit-source-id: ac253ecf577a29044c47c3fe254a01e71404c44c
