Kevin Risden commented on SOLR-9852:
------------------------------------

[~saumitras] - As far as I know no one is working on this currently. When I 
first worked on the SQL integration with Solr, I was able to get a JDBC-ODBC 
bridge to work. 

 

You would need to figure out what the stack trace is and find the exact method 
that needs to be implemented. There are a LOT of different places where 
metadata can be pulled from. Once you have the exact stack trace, then you can 
work on implementing the proper return metadata.
