Change Data Capture, how it works in Talend?

I have read Talend has change data capture. Can you please describe in details:
1) how it works
2) do you support Oracle in particular and may be a DB2 as a source?
3) Is it a log-based, meaning read transaction logs or have a trigger based mechanism
The reference to documentation would be helpful
Thanks,
Mike

Hi Chendra Sekhar G
Please have a look at document about TalendHelpCenter0683p000009MACJ.pngatabase+support+for+CDC.

Hi Sabrina,
Thanks for the reply.
I have been through all these support links.
Issue 1: (tMsSqlCDC) But if we observe in repository -> metadata -> dbConnection, for Oracle "CDC Function" folder is available but not for My SQL server connection where we can enable CDC on the server.
Issue 2: (tOracleCDC) 
we have enabled the CDC on Oralce 11g server(source) and when we are adding CDC on a specific table I have been getting the error messages. 
Please refer  the link posted by djugal user where I have been getting the same error.
it would be great if we get the help asap on how to fix them.
Question: I found that Logging mode is available for Oracle but not for SQL server which is having only trigger mode, is it right?

Hi Sabrina,
Yes, I am using Talend MDM platform and we want a real time synchronization between Neo4j Database and Talend MDM.
But As per the link provided by you Talend doesn't support CDC type logic for No SQL databases.
Please Guide.

Hi,
So far,  Talend doesn't support CDC type for  Neo4j  databases.
Feel free to create a new feature jira issue on Talend Bug Tracker.
