Nicholas Jiang created FLINK-17610: -------------------------------------- Summary: Align the behavior of result of internal map state to return empty iterator Key: FLINK-17610 URL: https://issues.apache.org/jira/browse/FLINK-17610 Project: Flink Issue Type: Improvement Components: Runtime / State Backends Affects Versions: 1.11.0 Reporter: Nicholas Jiang
There are different behaviors of result of internal map state. For HeapMapState, #entries(), #keys(), #values(), and #iterator() would all return null. However, for RocksDBMapState, #entries() would return null, while #keys(), #values(), #iterator() would return empty iterator. UserFacingMapState would align these behaviors to empty iterator for users, therefore this should better align these internal behavior to return empty iterator instead of null. -- This message was sent by Atlassian Jira (v8.3.4#803005)
