log
In the InnoDB context, "log" or "log files" typically refers to the redo log represented by the ib-logfile* files. Another log area, which is physically part of the system tablespace, is the undo log.
Other kinds of logs that are important in MariaDB are the error log, binary log, the general query log, and the slow query log.
