(was: Make Change Data Capture (CDC) processor for MySQL referring to GTID)
> Make Change Data Capture (CDC) processor for MySQL refer 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
> Priority: Major
>
> 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.
