/**
 * Used for row-based binary logging. This event precedes each row operation event. 
 * It maps a table definition to a number, where the table definition consists of 
 * database and table names and column definitions. The purpose of this event is to 
 * enable replication when a table has different definitions on the master and slave. 
 * Row operation events that belong to the same transaction may be grouped into sequences, 
 * in which case each such sequence of events begins with a sequence of TABLE_MAP_EVENT events: 
 * one per table used by events in the sequence.
