Yanqin Jin fe1147db1c Let DBSecondary close files after catch up (#6114 An error occurred ) ... Summary: After secondary instance replays the logs from primary, certain files become obsolete. The secondary should find these files, evict their table readers from table cache and close them. If this is not done, the secondary will hold on to these files and prevent their space from being freed. Test plan (devserver): ``` $./db_secondary_test --gtest_filter=DBSecondaryTest.SecondaryCloseFiles $make check $./db_stress -ops_per_thread=100000 -enable_secondary=true -threads=32 -secondary_catch_up_one_in=10000 -clear_column_family_one_in=1000 -reopen=100 ``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/6114 Differential Revision: D18769998 Pulled By: riversand963 fbshipit-source-id: 5d1f151567247196164e1b79d8402fa2045b9120		5 years ago
