Summary: Add some flags for configuring an SstFileManager. An SstFileManager is only created when one or more of these flags are set. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6454 Test Plan: - ran it a while: ``` $ python ./tools/db_crashtest.py blackbox --simple -max_key=100000 -write_buffer_size=131072 -target_file_size_base=131072 -max_bytes_for_level_base=524288 -value_size_mult=33 --interval=10 -max_background_compactions=4 -max_background_flushes=2 -sst_file_manager_bytes_per_sec=1048576 ``` - verified with strace the SstFileManager is behaving as configured: ``` $ strace -fp `pidof db_stress` -e ftruncate,unlink ... [pid 3074805] ftruncate(9</tmp/rocksdb_crashtest_blackbox6OJywh/000070.sst.trash>, 67423) = 0 [pid 3074805] ftruncate(9</tmp/rocksdb_crashtest_blackbox6OJywh/000070.sst.trash>, 51039) = 0 [pid 3074805] ftruncate(9</tmp/rocksdb_crashtest_blackbox6OJywh/000070.sst.trash>, 34655) = 0 [pid 3074805] ftruncate(9</tmp/rocksdb_crashtest_blackbox6OJywh/000070.sst.trash>, 18271) = 0 [pid 3074805] ftruncate(9</tmp/rocksdb_crashtest_blackbox6OJywh/000070.sst.trash>, 1887) = 0 [pid 3074805] unlink("/tmp/rocksdb_crashtest_blackbox6OJywh/000070.sst.trash") = 0 ... ``` Differential Revision: D20103315 Pulled By: ajkr fbshipit-source-id: b3e1092747157459d244b047947a979b85c98f48
