John Watson commented on FLINK-38934:
-------------------------------------
I would like to add a fix for this.
This can be used as a workaround for FLINK-38904 by forcing an earlier TLS
version, eliminating the issue.
> Debezium config 'binlog.ssl.protocol' is ignored
> ------------------------------------------------
>
> Key: FLINK-38934
> URL: https://issues.apache.org/jira/browse/FLINK-38934
> Project: Flink
> Issue Type: Bug
> Components: Flink CDC
> Reporter: John Watson
> Priority: Major
>
> When providing debeziumProperties in
> `org.apache.flink.cdc.connectors.mysql.source.MySqlSource`,
> `binlog.ssl.protocol` setting is ignored. This can be useful to specify a
> particular ssl protocol.
>
> Current state:
> binlog.ssl.protocol config in debeziumProperties is ignored
> Desired:
> binlog.ssl.protocol config in debeziumProperties is honoured, and
> binlogclient will be configured to use the specified protocol.
>
> e.g.
> {code:java}
> Properties debeziumProps = new Properties();
> debeziumProps.setProperty("binlog.ssl.protocol", "TLSv1.2");
> MySqlSource.builder().debeziumProperties(debeziumProps)...
> {code}
