Encapsulate some http interfaces for better management and maintenance of doris clusters.
The http interface includes getting cluster connection information, node information, node configuration information, batch modifying node configuration, and getting query profile.
For details, please refer to the document:
`docs/zh-CN/administrator-guide/http-actions/fe/manager/`
make doriswriter of DataX support format csv. Format csv is more simple and faster than
format json when data is simple
add property format: csv/json
add property column_separator: effect when format is csv, for example "\x01" , "^", etc...
Fix#6366
There is a bloom filter for each data page in a column which has bloom filter index.
`_has_null` flag can help to judge whether `null` exists in a data page.
If `null` value is added to a data page, `_has_null` will be set `true`.
After bloom filter for a data page finished, `_has_null`should be reset to `false` to prepare for next data page.
- Make load_parallelism configurable.
- Different clusters should be configured with different load_parallelism values.
- Some user don't know how to set load_parallelism, or don't know the best load_parallelism value.
This commit is the first stage of #6287
In this commit, we support:
1、Sync Job
1)、 Creating sync job and data channel in Fe.
2)、Pause sync job.
3)、Resume sync job.
4)、Stop sync job.
5)、Show sync jobs.
2、Canal
1)、Subscribing and getting the binlog data of canal with creating syncjob.
```
SELECT count(distinct products_id) FROM a_table as a WHERE 1=1 AND products_id in ( SELECT products_id from b_table );
```
Because hash table construction errors may lead to unstable results
The system view names in information_schema are case-insensitive,
but we should not refer to one of these using different cases within the same statement.
The following sql is correct：
```
select * from information_schema.TAbles where TAbles.ENGINE = 'Doris';
```
The following sql is wrong because `TAbles` and `tables` are used:
```
select * from information_schema.TAbles order by tables.CREATE_TIME;
```
The problem I want to solve is described in #6355.
This CL mainly changes:
1. Support compacting tablets under alter operations
On BE side, the compaction logic will select tablets which state is "TABLET_NOTREADY" to do cumulative compaction.
2. Remove "alter_task" field in tablet's meta on BE side.
"alter_task" field is never used long time ago
3. Support doing delete operation when table is doing alter operation.
Previously, when a table is doing alter operation, execution of delete will return error: Table's state is not NORMAL.
But now, delete can be executed successfully only if the condition column is not under schema change.
And delete condition will be applied to all materialized indexes.
1. `StorageEngine::_delete_tablets_on_unused_root_path` will try to obtain tablet shard write lock in `TabletManager`
```
StorageEngine::_delete_tablets_on_unused_root_path
TabletManager::drop_tablets_on_error_root_path
obtain each tablet shard's write lock
```
2. `TabletManager::build_all_report_tablets_info` and other methods will obtain tablet shard read lock frequently.
So, `StorageEngine::_delete_tablets_on_unused_root_path` will hold `_store_lock` for a long time.
This will make it difficult for other threads to get write `_store_lock`, such as `StorageEngine::get_stores_for_create_tablet`
`drop_tablets_on_error_root_path` is a small probability event, `TabletManager::drop_tablets_on_error_root_path` should return when its param `tablet_info_vec` is empty
Currently, Doris supports loading OSS/S3A files by using params like fs.s3a.access.key, but there is a bug when using it to load such type files. The root cause is broker can not handle FSDataInputStream which does not implement ByteBufferReadable.
See Issue #6307
S3A input stream to support ByteBufferReadable

SHOW DATA SKEW FROM tbl PARTITION(p1)
to view the data distribution of a specified partition
```
mysql> admin show data skew from tbl1 partition(tbl1);
+-----------+-------------+-------+---------+
| BucketIdx | AvgDataSize | Graph | Percent |
+-----------+-------------+-------+---------+
| 0 | 0 | | 100.00% |
+-----------+-------------+-------+---------+
1 row in set (0.01 sec)
```
Also modify the result of `admin show replica distribution`, add replica size distribution
```
mysql> admin show replica distribution from tbl1 partition(tbl1);
+-----------+------------+-------------+----------+------------+-----------+-------------+
| BackendId | ReplicaNum | ReplicaSize | NumGraph | NumPercent | SizeGraph | SizePercent |
+-----------+------------+-------------+----------+------------+-----------+-------------+
| 10002 | 1 | 0 | > | 100.00% | | 100.00% |
+-----------+------------+-------------+----------+------------+-----------+-------------+

Use `commitAsync` to commit offset to kafka, instead of using `commitSync`, which may block for a long time.
Also assign a group.id to routine load if user not specified "property.group.id" property, so that all consumer of
this job will use same group.id instead of a random id for each consume task.
```
alter routine load for cmy2 from kafka("kafka_broker_list" = "ip2:9094", "kafka_topic" = "my_topic");
```
This is useful when the kafka broker list or topic has been changed.
Also modify `show create routine load`, support showing "kafka_partitions" and "kafka_offsets".
Fix#6316
If the size of memtable is greater than max segment size and the memtable will flush more than
one segment file. BE coredump will be triggered when flushing memtable.
