## Proposed changes Issue Number: close #xxx In current segment cache, the key is rowset_id and the value is the vector of segments. And the segment cache size comes from be/src/runtime/exec_env_init.cpp. ``` uint64_t fd_number = config::min_file_descriptor_number; struct rlimit l; int ret = getrlimit(RLIMIT_NOFILE, &l); fd_number = static_cast<uint64_t>(l.rlim_cur); uint64_t segment_cache_capacity = fd_number * 2 / 5; SegmentLoader::create_global_instance(segment_cache_capacity); ``` Even the segment cache capacity is calculated by fd_number * 2 / 5. There's still some probability that the problem 'too many open file' will trigger. So we need more granular statistics. <!--Describe your changes.--> ## Further comments If this is a relatively large or complex change, kick off the discussion at [[email protected]](mailto:[email protected]) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
