What can I do to keep the memory low and log files occupied less space without restarting Rocksdb

[imgoby]

With rocksdb, after running for a short time, the memory occupied by the application will change from 1G to 20G, and the log file will occupy 30G. After the application restarts, the initialization of rocksdb will take a long time, such as 10 minutes. The rocksdb log will be reduced from 30G to 300M, and the rocksdb memory will also be reduced a lot, which can be 1G.

What can I do to keep the memory low and log files occupied less space without restarting Rocksdb?
