1. closure should be managed by a unique ptr and released by brpc , should not hold by our code. If hold by our code, we need to wait brpc finished during cancel or close.
2. closure should be exception safe, if any exception happens, should not memory leak.
3. using a specific callback interface to be implemented by Doris's code, we could write any code and doris should manage callback's lifecycle.
4. using a weak ptr between callback and closure. If callback is deconstruted before closure'Run, should not core.
1. Fix memory issues in LoadStreamMgrTest.
2. Skip S3FileWriterTest by default because it depends on the environment in teamcity.
3. Fix VTimestampFunctionsTest.convert_tz_test.
1.Reconstruct the logic of decode to read parquet. The parquet reader first reads the data according to the parquet physical type, and then performs a type conversion.
2.Support hive alter table.
This pr makes three changes to the display of complex types：
1. NULL value in complex types refers to being displayed as `null`, not `NULL`
2. struct type is displayed as "column_name": column_value
3. Time types such as `datetime` and `date`, are displayed with double quotes in complex types. like
`{1, "2023-10-26 12:12:12"}`
This pr also do a code refactor:
1. nesting_level is set to a member variable of the `DataTypeSerDe`, rather than a parameter in methods.
What's more, this pr fix a bug that fileSize is not correct, introduced by this pr: #25854
The sink who creates the delta writer may be closed while other sinks still using this delta writer.
The parent profile is deconstructed and when the last sink trying to update the profile, it will meet use-after-free.
To address this issue, we record the profile number in delta writer,
and the last sink who close the delta writer will create and update the profile.
this PR #22602 have check function.
only support date_trunc(column, const), so the second must be const literal
and no need to check time unit every row.
* Optimize fetch delete predicates
* Fix incorrect query result when compaction eliminate delete predicates between `NewOlapScanNode::_init_scanners` and `NewOlapScanner::init`
* Fix be ut
Now we can not support streamload with column which is map/array nested map/array
serde can do this now , so we can replace it
Notice. if item data in complex type data is empty we just return error, instead of makeup default value , because now we can not define right default for complex type
