Xinyi Zou 85362a907e [fix](mem tracker) Fix some memory leaks, inaccurate statistics, core dump, deadlock bugs (#10072 )

1. Fix the memory leak. When the load task is canceled, the `IndexChannel` and `NodeChannel` mem trackers cannot be destructed in time.
2. Fix Load task being frequently canceled by oom and inaccurate `LoadChannel` mem tracker limit, and rewrite the variable name of `mem limit` in `LoadChannel`.
3. Fix core dump, when logout task mem tracker, phmap erase fails, resulting in repeated logout of the same tracker.
4. Fix the deadlock, when add_child_tracker mem limit exceeds, calling log_usage causes `_child_trackers_lock` deadlock.
5. Fix frequent log printing when thread mem tracker limit exceeds, which will affect readability and performance.
6. Optimize some details of mem tracker display.

Apache Doris (incubating)

Doris is an MPP-based interactive SQL data warehousing for reporting and analysis. Its original name was Palo, developed in Baidu. After donated to Apache Software Foundation, it was renamed Doris.

Doris provides high concurrent low latency point query performance, as well as high throughput queries of ad-hoc analysis.
Doris provides batch data loading and real-time mini-batch data loading.
Doris provides high availability, reliability, fault tolerance, and scalability.

The main advantages of Doris are the simplicity (of developing, deploying and using) and meeting many data serving requirements in a single system. For details, refer to Overview.

Official website: https://doris.apache.org/

Note

Some licenses of the third-party dependencies are not compatible with Apache 2.0 License. So you need to disable some Doris features to be complied with Apache 2.0 License. For details, refer to the thirdparty/LICENSE.txt

Technology

Doris mainly integrates the technology of Google Mesa and Apache Impala, and it is based on a column-oriented storage engine and can communicate by MySQL client.
