do not check compiler's version inenv.sh, because building broker does not need gcc compiler. And the version is also checked in CMakefile
Issue Number: close#20948
Fix read error in mixed partition locations(for example, some partitions locations are on s3, other are on hdfs) by `getLocationType` of file split level instead of the table level.
after we introduce "PushdownFilterThroughProject" post processor, some plan node missed their groupExpression (withChildren function will remove groupExpression).
this is not good for debug, since it takes more time to find the owner group of a plan node
This pr record the missing owner group id in plan node mutableState.
`Wrong data type for column` error when column order in hive table is not same in orc file schema.
The root cause is in order to handle the following case:
The table in orc format of Hive 1.x may encounter system column names such as `_col0`, `_col1`, `_col2`... in the underlying orc file schema, which need to use the column names in the hive table for mapping.
### Solution
Currently fix this issue by handling the following case by specifying hive version to 1.x.x in the hive catalog configuration.
```sql
CREATE CATALOG hive PROPERTIES (
'hive.version' = '1.x.x'
);
```
There is a significant performance improvement in serializing keys in the aggregate node through vectorization. Now, applying it to the join node also brings performance improvement.
1. fix storage prefix for obj file cache: oss/cos/obs don't need convert to s3 prefix , just convert when create split
2. dlf iceberg catalog: support dlf iceberg table, use s3 file io.
If the current query is running for a very long time, the ExecTime of this query may larger than the MAX_INT value, then a NumberFormatException will be thrown when execute "show proc '/current_queries'."
The query's ExecTime is long type, we should not use 'Integer.parseInt' to parse it.
If there is only one fragment of a query plan, FE will call `exec_plan_fragment` rpc to BE.
And on BE side, the `exec_plan_fragment()` will be executed directly in bthread, but it may call
some JNI method like `AttachCurrentThread()`, which will return error in bthread.
So I modify the `exec_plan_fragment` to make sure it will be executed in pthread pool.
if table currently has no partition, the truncate SQL will be a empty command, it should directly return and avoid throwing IllegalStateException caused by bufferSize equals zero

Fix tow bugs:
COW & Read Optimized table will use hive splitter to split files, but it can't recognize some specific files.

To_date function in nereids return type should be DATEV2 if the arg type is DATETIMEV2.
Before the return type was DATE which would cause BE get wrong query result.
Support rf into left outer join from outside allowed type join.
Before this pr, some join type, such as full outer join, are all not allowed to do rf pushing.
For example, (a left join b on a.id = b.id) inner join c on a.id2 = c.id2, will lost the rf pushing from c.id2 to inner table a.
This pr will open this limitation for supporting rf into left outer join from outside allowed type join.
During physical set operation translation, we forget to inherit rf related info from set op children, which will lead the merge filter error and get a long waittime.

We use the time wheel algorithm to complete the scheduling and triggering of periodic tasks. The implementation of the time wheel algorithm refers to netty's HashedWheelTimer.
We will periodically (10 minutes by default) put the events that need to be triggered in the future cycle into the time wheel for periodic scheduling. In order to ensure the efficient triggering of tasks and avoid task blocking and subsequent task scheduling delays, we use Disruptor to implement the production and consumption model.
When the task expires and needs to be triggered, the task will be put into the RingBuffer of the Disruptor, and then the consumer thread will consume the task.
Consumers need to register for events, and event registration needs to provide event executors. Event executors are a functional interface with only one method for executing events.
If it is a single event, the event definition will be deleted after the scheduling is completed; if it is a periodic event, it will be put back into the time wheel according to the periodic scheduling after the scheduling is completed.
When compiling FunctionArrayEnumerateUniq::_execute_by_hash, AllocatorWithStackMemory::free(buf)
will be called when delete HashMapContainer. the gcc compiler will think that size > N and buf is not heap memory,
and report an error ' void free(void*)' called on unallocated object 'hash_map'
