* feat: remove own greatest fn (#5994) * fix: prune primary key with multiple columns may use default value as statistics (#5996) * test: incorrect test result when filtering pk with multiple columns * fix: prune non first tag correctly Distinguish no column and no stats and only use default value when no column * test: update test result * refactor: rename test file * test: add test for null filter * fix: use StatValues for null counts * test: drop table * test: fix unstable flow test * fix: check if memtable is empty by stats (#5989) fix/checking-memtable-empty-and-stats: - **Refactor timestamp updates**: Simplified timestamp range updates in `PartitionTreeMemtable` and `TimeSeriesMemtable` by replacing `update_timestamp_range` with `fetch_max` and `fetch_min` methods for `max_timestamp` and `min_timestamp`. - Affected files: `partition_tree.rs`, `time_series.rs` - **Remove unused code**: Deleted the `update_timestamp_range` method from `WriteMetrics` and removed unnecessary imports. - Affected file: `stats.rs` - **Optimize memtable filtering**: Streamlined the check for empty memtables in `ScanRegion` by directly using `time_range`. - Affected file: `scan_region.rs` * chore: bump version to 0.14.1 Signed-off-by: Zhenchi <zhongzc_arch@outlook.com> --------- Signed-off-by: Zhenchi <zhongzc_arch@outlook.com> Co-authored-by: dennis zhuang <killme2008@gmail.com> Co-authored-by: Yingwen <realevenyag@gmail.com> Co-authored-by: Lei, HUANG <6406592+v0y4g3r@users.noreply.github.com>
