[QUESTION] Is the alerts based mechanism being used? #111

Hi,

We are planning to use Databus to implement CDC on Oracle database. We have a couple of questions that I would appreciate if anybody can help.

As we understand, reading the Wiki (https://github.com/linkedin/databus/wiki/Databus-2.0-relay-design), the Oracle Database Event Producer periodically polls database to get the changes, but in the Databus Oracle page (https://github.com/linkedin/databus/wiki/Connecting-Databus-to-an-Oracle-Database) also a system based in alerts is described and it can be configured in the table sync_core_settings. Checking the code, we think that use is not implemented. Could you confirm if we are correct? If not, do you know why is it implemented? Perhaps, it’s not a recommended usage

Another question is how the the table where trigger is inserting the changes is cleaned up?

Thanks very much in advance.
