Hi everyone I m thinking on using flink cdc for one of our project and thinking using about incremental snapshot approach is it not seeme to be production ready and in experimental mode

Flink CDC is not experimental. It’s production ready but the configuration and production deployment plans needs to be carefully prepared. You also should be on Flink 1.19 or 1.19.1 ideally.

Flink cdc is not experimental I know but what about snapshot based approach in latest document it is mentioned as experimental

Can you send a link to the documentation that lists this as experimental?

So you are referring to this section ? “The Oracle CDC connector can also be a DataStream source. There are two modes for the DataStream source: • incremental snapshot based, which allows parallel reading • SourceFunction based, which only supports single thread reading Incremental Snapshot based DataStream (Experimental) #”

Yes

Ok, well it’s quite clear that for the Oracle CDC Connector as a Incremental Snapshot into DataStream its in experimental status at the moment. Hopefully you will hear back from those with experience using it.

Yes I m not interested in source based CDC because it is using embedded debezium and we have already raised bugs to debezium when doing a poc with it for oracle events and they are very slow in resolving those bugs I m more into incremental snapshot based datastream ,any other alternative to capture oracle CDC if you have used any

I notice that MySQL CDC Connector also seems to have incremental snapshots but it does not say experimental. Then again it does not say into DataStream …

Yes standalone debezium has issues with oracle connector in case of heavy transactions it is lossing some data so we decided to look into alternative flink do have snapshot based reading but that is experimental so we can't go with that

You could take a look at Striim

You have used striim??

No I have not. But the commercial solution from Oracle was the GoldenGate purchase and that same team now offers Striim product. So its probably of high quality I would guess
