How to configure Kafka JDBC Source Connector with stored procedure?

I am very new to Kafka, I'm doing a PoC (my first Kafka app) and was curious to know if anyone has come across or worked on a custom JDBC Source Connector that uses a stored procedure to export data from Oracle into Kafka?
I know this could be considered an open-ended question by the SO community but thanks for your patience and I'd appreciate any feedback.
Thank you!
Some background:
I already have stored procedures in Oracle which are used by an existing Spring app to extract and load data in a new DB (for a new version of an existing enterprise application).
The table structure in the new database is different than that of the old.
The Spring app (which uses Spring JDBC and works with Stored Procedures, Row Mappers etc.) was developed as a PoC to check connectivity, integration and to load data in the new DB.
Now that it works, we're trying to introduce Kafka that would actually store the data and then load it into the new DB. The JDBC Sink Connector would be developed later.
I am looking for an example (using Java, Maven, Spring) that would help me in getting started towards building a custom connector. Most of the example/docs show curl examples which doesn't fit my existing app. I maybe missing something here.
There is way that we can call SP though source connector property - query: call sp here by creating temp table and insert data

Hibernate dialect Issues with update to Oracle 12.2 C database when using Grails

We are running Grails 2.3.11 on JRE 1.8_211. We have Hibernate version - 3.6.10.6.
When we were working with Oracle 11, it was working fine but when I upgrade to 12.2C, we get following error:-
org.codehaus.groovy.grails.orm.hibernate.exceptions.CouldNotDetermineHibernateDialectException: Could not determine Hibernate dialect for database name [Oracle]!
On reverting back to Oracle 11, the issue gets resolved.
Can anyone please suggest a solution for migrating my application to Oracle 12.2C.
We had not specified the hibernate dialect in one of the datasources in datasource.groovy.
It seems that in oracle 12C, it is mandatory to specify the dialect for each data source even though it is not mandatory for Oracle 11g.
Hence, during migrating from Oracle 11g to Oracle 12C, please add verifying that dialects are explicitly specified in your checklist.
Hope this helps others.

Make BIRT report using data from Gemfire cache

I am relatively new to both, BIRT and gemfire but I know the basics. Thought I wasn't able to find how BIRT can fetch data from gemfire cache.
Can someone please help me on the procedure or whether it is possible or not?
It looks like BIRT uses JDBC (amongst other means) to talk to a backend datasource. Unfortunately GemFire does not provide a JDBC driver. You would need to develop a custom ODA Data Source as described here: https://wiki.eclipse.org/Use_Case_-_Create_a_Custom_ODA_Data_Source
