englefly opened a new pull request, #10254:
URL: https://github.com/apache/doris/pull/10254

   # Proposed changes
   1. if flush thread pool already have tasks waiting in queue, wait at most 2 sec
   compared with current strategy, it could avoid flushing small segment files
   2. After waiting for 2 sec, if the thread pool is still overloaded, we choose the delta_writer whose current mem-table is big, the submitted mem-table is not counted.
   3. when mem exceeded, the size of mem to reduce is calculated by the _mem_tracker->consumption(), not by _mem_tracker->limit().
