### What problem does this PR solve? <!--add issue link with summary if exists--> #571 ### What is changed and how it works? RocksDB database will automatically persist its current set of options into a file since RocksDB 4.3[1], so when DB exit, we should reopen the rocksdb instance using the options file stored in the db directory. If store usage scenario into meta column family, we need to open DB with default options and then read meta data and set options, that would also lead to unexpected flushs and compactions.
