Summary: It is too slow that our `db_crashtest.py` often kills `db_stress` before the setup phase completes. Profiled it and found a few ways to optimize. Pull Request resolved: https://github.com/facebook/rocksdb/pull/9475 Test Plan: Measured setup phase time reduced 22% (36 -> 28 seconds) for first run, and 36% (38 -> 24 seconds) for non-first run on empty-ish DB. - first run benchmark command: `rm -rf /dev/shm/dbstress*/ && mkdir -p /dev/shm/dbstress_expected/ && ./db_stress -max_key=100000000 -destroy_db_initially=1 -expected_values_dir=/dev/shm/dbstress_expected/ -db=/dev/shm/dbstress/ --clear_column_family_one_in=0 --reopen=0 --nooverwritepercent=1` output before this PR: ``` 2022/01/31-11:14:05 Initializing db_stress ... 2022/01/31-11:14:41 Starting database operations ``` output after this PR: ``` ... 2022/01/31-11:12:23 Initializing db_stress ... 2022/01/31-11:12:51 Starting database operations ``` - non-first run benchmark command: `./db_stress -max_key=100000000 -destroy_db_initially=0 -expected_values_dir=/dev/shm/dbstress_expected/ -db=/dev/shm/dbstress/ --clear_column_family_one_in=0 --reopen=0 --nooverwritepercent=1` output before this PR: ``` 2022/01/31-11:20:45 Initializing db_stress ... 2022/01/31-11:21:23 Starting database operations ``` output after this PR: ``` 2022/01/31-11:22:02 Initializing db_stress ... 2022/01/31-11:22:26 Starting database operations ``` - ran minified crash test a while: `DEBUG_LEVEL=0 TEST_TMPDIR=/dev/shm python3 tools/db_crashtest.py blackbox --simple --interval=10 --max_key=1000000 --write_buffer_size=1048576 --target_file_size_base=1048576 --max_bytes_for_level_base=4194304 --value_size_mult=33` Reviewed By: anand1976 Differential Revision: D33897793 Pulled By: ajkr fbshipit-source-id: 0d7b2c93e1e2a9f8a878e87632c2455406313087 |
