General query log	Established client connections and statements received from clients
Binary log	Statements that change data (also used for replication)
Relay log	Data changes received from a replication source server
Slow query log	Queries that took more than long_query_time seconds to execute
DDL log (metadata log)	Metadata operations performed by DDL statements
