Description
When connecting to a MySQL cluster consisting of multiple hosts, existing CDC processor can not automatically switch to other host when the connected host goes down.
The reason is that file names and positions of binary log may be different for each host in the same cluster.
In such a case it is impossible to continue reading files from the same position.
In order to continue reading in such cases, a processor referring to the GTID (Global Transaction ID) is necessary.
GTID is ID that uniquely identifies a transaction, and it is recorded in binary log of MySQL.
