-------------------------------------
Summary: RocksDB keys iterator performance improvement
Key: FLINK-37324
URL: https://issues.apache.org/jira/browse/FLINK-37324
Project: Flink
Issue Type: Improvement
Components: Runtime / State Backends
Affects Versions: 2.0-preview
Reporter: Gabor Somogyi
The are checks in
[RocksStateKeysIterator|https://github.com/apache/flink/blob/cd0cfe42c15042a3c27a0c341416aa32c0d594b6/flink-state-backends/flink-statebackend-rocksdb/src/main/java/org/apache/flink/state/rocksdb/iterator/RocksStateKeysIterator.java#L68]
and in
[RocksMultiStateKeysIterator|https://github.com/apache/flink/blob/9bcc41dc233c754a119e188d8801b48ff3fb434f/flink-state-backends/flink-statebackend-rocksdb/src/main/java/org/apache/flink/state/rocksdb/iterator/RocksMultiStateKeysIterator.java#L168]
(maybe other places too) which looks never can happen. If it can be proven and
can be removed then it would be a performance gain.
