> Currently it is only possible to run SQL queries against CSV files. I would
> like to be able to run SQL queries against data that is already loaded into
> memory in a single RecordBatch or an iterator over RecordBatch.
> There are two reasons I want this feature:
> # Ability to call DataFusion via IPC or JNI from Java to run queries
> # Ability to create benchmarks for the query engine that do not involve disk
> I/O
