1. optimize error message when using batch delete
2. rename session variable is_report_success to enable_profile
3. add table name to OlapScanner profile
This CL mainly changes:
1. Add star schema benchmark tools in `tools/ssb-tools`, for user to easy load and test with SSB data set.
2. Disable the segment cache for some read scenario such as compaction and alter operation.(Fix#6924 )
3. Fix a bug that `max_segment_num_per_rowset` won't work(Fix#6926)
4. Enable `enable_batch_delete_by_default` by default.
1. Simplify the use of flink connector like other stream sink by GenericDorisSinkFunction.
2. Add the use cases of flink connector.
## Use case
```
env.fromElements("{\"longitude\": \"116.405419\", \"city\": \"北京\", \"latitude\": \"39.916927\"}")
.addSink(
DorisSink.sink(
DorisOptions.builder()
.setFenodes("FE_IP:8030")
.setTableIdentifier("db.table")
.setUsername("root")
.setPassword("").build()
));
```
With thirdparties 1.4.0 to 1.4.1
1. Add patch for aws-c-cal-0.4.5
2. Add some solutions for `undefined reference libpsl`
3. Move libgsasl to fix link problme of libcurl.
4. Downgrade openssl to 1.0.2k to fix problem of low version glibc
some user do not know Doris support type boolean, they use TINYINT,
so i add type BOOLEAN when enter 'help create table' in mysql client.
currently, type BOOLEAN size is 1 byte, but the value of boolean column only in {0,1} ,
which waste some memory, and i want change it's implement to 1 bit in the future.
1. Refactor the create method of hdfs reader & writer.
libhdfs3 does not support arm64. So we should not support hdfs reader & writer on arm64.
2. And micro for LowerUpperImpl
```
EXPORT TABLE xxx
...
PROPERTIES
(
"label" = "mylabel",
...
);
```
And than user can use label to get the info by SHOW EXPORT stmt:
```
show export from db where label="mylabel";
```
For compatibility, if not specified, a random label will be used. And for history jobs, the label will be "export_job_id";
Not like LOAD stmt, here we specify label in `properties` because this will not cause grammatical conflicts,
and there is no need to modify the meta version of the metadata.
I tested hex in a 1000w times for loop with random numbers，
old hex avg time cost is 4.92 s，optimize hex avg time cost is 0.46 s which faster nearly 10x.
1. This bug is introduced from #6582
2. Optimize the error log of Address used used error msg.
3. Add some document about compilation.
1. Add a custom thirdparty download url.
2. Add a custom com.alibaba maven jar package for DataX.
4. Fix bug that BE crash when closing scan node, introduced from #6622.
* [Bug]:fix when data null , throw NullPointerException

1. Fix bug of UNKNOWN Operation Type 91
2. Support using resource_tag property of user to limit the usage of BE
3. Add new FE config `disable_tablet_scheduler` to disable tablet scheduler.
4. Add documents for resource tag.
5. Modify the default value of FE config `default_db_data_quota_bytes` to 1PB.
6. Add a new BE config `disable_compaction_trace_log` to disable the trace log of compaction time cost.
7. Modify the default value of BE config `remote_storage_read_buffer_mb` to 16MB
8. Fix `show backends` results error
9. Add new BE config `external_table_connect_timeout_sec` to set the timeout when connecting to odbc and mysql table.
10. Modify issue template to enable blank issue, for release note or other specific usage.
11. Fix a bug in alpha_row_set split_range() function.
In some cases, the query plan thrift structure of a query may be very large
(for example, when there are many columns in SQL), resulting in a large number
of "send fragment timeout" errors.
This PR adds an FE config to control whether to transmit the query plan in a compressed format.
Using compressed format transmission can reduce the size by ~50%. But it may reduce
the concurrency by ~10%. Therefore, in the high concurrency small query scenario,
you can choose to turn off compaction.
Support hdfs in select outfile clause without broker.
This PR implement a HDFS writer in BE which is used to write HDFS file directly without using broker.
Also the hdfs outfile clause syntax check has been added in FE.
The syntax:
```
select * from xx into outfile "hdfs://user/outfile_" format as csv
properties ("hdfs.fs.dafultFS" = "xxx", "hdfs.hdfs_user" = "xxx");
```
Note that all hdfs configurations need to carry a prefix `hdfs.`.
1. Fix a memory leak in `collect_iterator.cpp` (Fix#6700)
2. Add a new BE config `max_segment_num_per_rowset` to limit the num of segment in new rowset.(Fix#6701)
3. Make the error msg of stream load more friendly.
This pr mainly supports
1. Export query result sets concurrently
2. Query result set export supports s3 protocol
Among them, there are several preconditions for concurrently exporting query result sets
1. Enable concurrent export variables
2. The query itself can be exported concurrently
(some queries containing sort nodes at the top level cannot be exported concurrently)
3. Export the s3 protocol used instead of the broker
After exporting the result set concurrently,
the file prefix is changed to outfile_{query_instance_id}_filenumber.{file_format}
