sdong 36c504be17 Avoid create directory for every column families (#6358) ... Summary: A relatively recent regression causes for every CF, create and open directory is called for the DB directory, unless CF has a private directory. This doesn't scale well with large number of column families. Pull Request resolved: https://github.com/facebook/rocksdb/pull/6358 Test Plan: Run all existing tests and see it pass. strace with db_bench --num_column_families and observe it doesn't open directory for number of column families.
