Description

My Mariadb server run out of space and crashed. It turned out that Rocksdb fills the hard drive with hundreds of log file like this
LOG.old.1560127923761254
Is there a way to have MariaDB remove the unneeded files automatically?
my version is
10.4.14-MariaDB-1:10.4.14+maria~bionic mariadb.org binary distribution

Yes, there is rocksdb_keep_log_file_num option which can be set in my.cnf or command line tells RocksDB how many files should be kept. The default (from RocksDB) is 1000.
