Is there any reason why a SQL format isn't is that list? Wondering if there's a way to join SQL sources with file storage sources. An example of this would be filtering or enrichment operations.

// sorry if this is a stupid question.

When you say SQL format do you mean being able to read the output of a jdbc or odbc driver? If this is the case then mostly just time. You are not the first person to ask about this and now that there are java bindings in cudf this might become easier to make a reality in the next few months.

Or do you mean being able to read a database's file format natively? If this is the case there are many reasons. 1. There are many poorly/non documented formats 2. Even if you decide to read some other DB's format natively, those formats change over time 3. Little control of how and where the data is laid out

Not a stupid question. The reason is priorities, but definitely our ideal to do predicate push down and join databases to files, streams, etc.
