Description
After testing DBZ-0.3.6 we have found more issues with MySQL-5.7.
Here is stacktrace we got :
[2016-12-23 11:52:51,833] ERROR Task patient-data-connector_trunk-10-0 threw an uncaught and unrecoverable exception (org.apache.kafka.connect.runtime.WorkerTask:142) org.apache.kafka.connect.errors.ConnectException: Unknown event type 38 at io.debezium.connector.mysql.AbstractReader.wrap(AbstractReader.java:164) at io.debezium.connector.mysql.AbstractReader.failed(AbstractReader.java:131) at io.debezium.connector.mysql.BinlogReader$ReaderThreadLifecycleListener.onEventDeserializationFailure(BinlogReader.java:655) Caused by: java.io.IOException: Unknown event type 38 at com.github.shyiko.mysql.binlog.event.deserialization.EventHeaderV4Deserializer.getEventType(EventHeaderV4Deserializer.java:45) at com.github.shyiko.mysql.binlog.event.deserialization.EventHeaderV4Deserializer.deserialize(EventHeaderV4Deserializer.java:35)
After some digging we found that mysql-binlog-connector (shipped with DBZ-0.3.6) supports all 36 event types according to official specs : https://dev.mysql.com/doc/internals/en/binlog-event-type.html
However, MySQL-5.7 source code indeed includes 38 event types : https://github.com/mysql/mysql-server/blob/71f48ab393bce80a59e5a2e498cd1f46f6b43f9a/libbinlogevents/include/binlog_event.h#L328
VIEW_CHANGE_EVENT= 37,
/* Prepared XA transaction terminal event similar to Xid */
XA_PREPARE_LOG_EVENT= 38,
Looks like MySQL folks haven't updated official docs after made enhancements.
Add please 37 and 38 event types to mysql-binlog-connector library
