Hi,
This is what I've understood so far, JDBC plugin in Feeder mode is run as a
bash script with parameters similar to river. The documentation says that
it is a push model. Can anyone explain how does it work? If i have a new
data pushed into my db, what role does the feeder play from here on?
Thank you.

The "push model" works like this: a standalone JVM is running the JDBC
plugin, this plugin connects to an Elasticsearch cluster using the
TransportClient. Then, SQL statement(s) are executed, the rows are
processed, and indexed into Elasticsearch with the bulk processor.
Because the nodes in the cluster are not "pulling" data from an external
source into the cluster JVMs like river instances do, the standalone JDBC
plugin JVM is what I call "push" model.
The JDBC plugin does not recognize if there is new data in the DB.
