what is the difference between a pipeline connector mysql and a source connecor mysql cdc?

[plum7ree]

Hello, thanks for the nice software.

I am trying to use a flink cdc and have found out there are two mysql connectors.

pipeline: https://nightlies.apache.org/flink/flink-cdc-docs-master/docs/connectors/pipeline-connectors/mysql/
source: https://nightlies.apache.org/flink/flink-cdc-docs-master/docs/connectors/flink-sources/mysql-cdc/

I had thought that a pipeline mysql is only for a snapshot,
but when I put the data into mysql, my kafka-sink got real time updated data.

So now I am very confused, what's the difference between those.

Can anyone explain what's the purpose of those two?
Does pipeline mysql connector also doing CDC job (there are option debezium on yaml file)?
Then why there is also a source mysql-cdc connector?
