What is the current behavior?
rocksdb's LOG file is unbounded and takes wayyyy too much space in production
What is the new behavior?
limit the number of rocksdb LOG files, and their size.
Set the rocksdb level to WARN, which will print a summary of all column stats (~100Ko) at startup only, whereas the INFO level will print it very regularily.
Plus, add a few more memtable metrics to prometheus endpoint.
Does this introduce a breaking change?
No
