## Description Fix aligned multi-measurement LAST queries that may hang when a time filter excludes the only remaining chunk after selected-column pruning. For aligned series, pruning chunks with no values in the selected measurements can leave a singleton chunk whose statistics differ from the time-series metadata statistics. `DiskAlignedChunkMetadataLoader` previously skipped time filtering when only one chunk remained, allowing an out-of-range chunk to enter the scan state machine without being consumed. ## Changes - Apply chunk-level time filtering to every non-empty aligned chunk metadata list, including singleton lists. - Add an integration test covering a multi-measurement LAST query whose selected measurements only exist outside the query time range. ## Testing - Added `IoTDBAlignedLastQueryWithTimeFilterIT`. - Not run locally. -- This is an automated message from the Apache Git Service.
