1. Fix a profile bug of `MergeRangeFileReader`, and add a profile `ApplyBytes` to show the total bytes of ranges.
2. There's no need to merge large columns, because `MergeRangeFileReader` will increase the copy time.
Like #15641, we should reduce the size of executables on macOS arm64. Otherwise, we can not run doris_be and doris_be_test with ASAN build type on macOS arm64 now.
Manually track query/load/compaction/etc. memory in Allocator instead of mem hook.
Can still use Mem Hook when cannot manually track memory code segments and find memory locations during debugging.
This will cause memory tracking loss for Query, loss less than 10% compared to the past, but this is expected to be more controllable.
Similarly, Mem Hook will no longer track unowned memory to the orphan mem tracker by default, so the total memory of all MemTrackers will be less than before.
Not need to get memory size from jemalloc in Mem Hook each memory alloc and free, which would lose performance in the past.
Not require caching bthread local in pthread local for memory hook, in the past this has caused core dumps inside bthread, seems to be a bug in bthread.
ThreadContext life cycle to manual control
In the past, ThreadContext was automatically created when it was used for the first time (this was usually in the Jemalloc Hook when the first malloc memory), and was automatically destroyed when the thread exited.
Now instead of manually controlling the create and destroy of ThreadContext, it is mainly created manually when the task thread start and destroyed before the task thread end.
Run 43 clickbench query tests.
Use MemHook in the past:
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.
