## Proposed changes Issue Number: this pr will pick part of #35457 to reduce the potential of dead lock with following example: 时间点 | create table线程1 | create table线程2 | table stat线程 | truncate线程 -- | -- | -- | -- | -- t1 | 获取表1的read lock | | | t2 | | 获取表2的read lock | | t3 | | | 尝试获取表1的write lock，被阻塞 | t4 | | | | 尝试获取表2的write lock，被阻塞 t5 | 尝试获取表2的read lock，由于前面有线程尝试获取表2的write lock，被迫排队 | | | t6 | | 尝试获取表1的read lock，由于前面有线程尝试获取表1的write lock，被迫排队 | | This PR places the updates of table statistics(such as data size/replica count) in the Table Stats Thread to be done on a scheduled basis, so that there is no need to add a read lock when obtaining table statistics. <!--Describe your changes.--> -- This is an automated message from the Apache Git Service.
