VARIABLE_TYPE ENUM
VARIABLE_COMMENT What form of binary logging the master will use: either ROW for row-based binary logging, STATEMENT for statement-based binary logging, or MIXED. MIXED is statement-based binary logging except for those statements where only row-based is correct: those which involve user-defined functions (i.e. UDFs) or the UUID() function; for those, row-based binary logging is automatically used.
