----------------------------------------
Summary: Make Change Data Capture (CDC) processor for MySQL
referring to GTID
Key: NIFI-5583
URL: https://issues.apache.org/jira/browse/NIFI-5583
Project: Apache NiFi
Issue Type: New Feature
Components: Extensions
Affects Versions: 1.7.1
Reporter: Yoshiaki Takahashi
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.
