SCDF - Create Metadata tables in different schema and work the Batch Job with different schema

问题


I'm using Spring Batch which loads data from Oracle and put it into the MongoDB. I'm looking to use the Spring Cloud Data Flow, but SCDF doesn't have support for the MongoDB.

Is there any way if we can maintain the SCDF Metadata into the Postgres (as its has good support) or H2, in this example I used H2, and run the actual batch jobs which load data from Oracle to MongoDB.

When I tried to run this combination, I get the below error, certainly some config changes needs to be tweek. Any quick workaround ? Error: org.springframework.bat
