in some case, we has code
```
if (_join_op == TJoinOp::RIGHT_OUTER_JOIN || _join_op == TJoinOp::FULL_OUTER_JOIN) {
_probe_column_convert_to_null = _convert_block_to_null(*input_block);
}
```
then do next function like cast , but in function cast we assume block column is same with from_type.which will make status error
* [Fix](partial-update) Fix partial update fail when the datetime default value is 'current_time' (#32926)
* Problem: When importing data that includes datetime with a default value of current time for partial column updates, the import fails.
Reason: Partial column updates do not handle the logic for datetime default values.
Solution: During partial column updates, when the default value is set to current time, read the current time from the runtime state and write it into the data.
* [Enhancement](partial update)Add timezone case for partial update timestamp #33177
* [fix](partial update) Support partial update when the date default value is 'current_date'. This PR is a extension of PR #32926. (#33394)
Following #25138, unified schema change interface for parquet and orc reader, and can be applied to other format readers as well.
Unified schema change interface for all format readers:
- First, read the data according to the column type of the file into source column;
- Second, convert source column to the destination column with type planned by FE.
Issue Number: #31442
- Add hive-writer runtime profiles.
- Change output file names to `${query_id}${uuid}-${index}.${compression}.${format}`. e.g. `"d8735c6fa444a6d-acd392981e510c2b_34fbdcbb-b2e1-4f2c-b68c-a384238954a9-0.snappy.parquet"`. For the same partition writer, when the file size exceeds `hive_sink_max_file_size`, the currently written file will be closed and a new file will be generated, in which ${index} in the new file name will be incremented, while the rest will be the same .
Fix failed in regression_test/suites/query_p0/group_concat/test_group_concat.groovy
select
group_concat( distinct b1, '?'), group_concat( distinct b3, '?')
from
table_group_concat
group by
b2
exception:
lowestCostPlans with physicalProperties(GATHER) doesn't exist in root group
The root cause is '?' is push down to slot by NormalizeAggregate, AggregateStrategies treat the slot as a distinct parameter and generate a invalid PhysicalHashAggregate, and then reject by ChildOutputPropertyDeriver.
I fix this bug by avoid push down literal to slot in NormalizeAggregate, and forbidden generate stream aggregate node when group by slots is empty
Previously, strings_pool was allocated within each tree node. However, due to the Arena's alignment of allocated chunks to at least 4K, this allocation size was excessively large for a single tree node. Consequently, when there are numerous nodes within the SubcolumnTree, a significant portion of memory was wasted. Moving strings_pool to the tree itself optimizes memory usage and reduces wastage, improving overall efficiency.
