Example 1 with GtidEventData

use of com.github.shyiko.mysql.binlog.event.GtidEventData in project debezium by debezium.

the class BinlogReader method handleGtidEvent.

/**
 * Handle the supplied event with a {@link GtidEventData} that signals the beginning of a GTID transaction.
 * We don't yet know whether this transaction contains any events we're interested in, but we have to record
 * it so that we know the position of this event and know we've processed the binlog to this point.
 * <p>
 * Note that this captures the current GTID and complete GTID set, regardless of whether the connector is
 * {@link MySqlTaskContext#gtidSourceFilter() filtering} the GTID set upon connection. We do this because
 * we actually want to capture all GTID set values found in the binlog, whether or not we process them.
 * However, only when we connect do we actually want to pass to MySQL only those GTID ranges that are applicable
 * per the configuration.
 *
 * @param event the GTID event to be processed; may not be null
