Hi guys, I don't think this is the right way to support different data sources. As we discussed in an earlier email, a better way to go about this, which is also extensible and maintainable, is to first extend the WayangRel Algebra, with specific table scan operators (e.g., one for Jdbc, one for csv, etc..) and write logical-to-physical rules. Each physical scan operator should then have methods for accessing sources. -- This is an automated message from the Apache Git Service.
