[I] Decide on sync vs async DataFrame methods [datafusion-java]
andygrove opened a new issue, #25:
URL: https://github.com/apache/datafusion-java/issues/25
### Is your feature request related to a problem or challenge?
The current design is using synchronous execution. In https://github.com/pgwhalen/datafusion-java everything seems to be async.
Let's decide how we want to handle this before we add too much more code.

While the old bindings in that repo present `CompletableFutures`, the newer ones I've written are synchronous. The work I've done is all on the [datafusion-ffi-java](https://github.com/pgwhalen/datafusion-java/tree/datafusion-ffi-java) branch in the `datafusion-ffi-*` directories, and I decided to follow the pattern this repo uses: presenting synchronous java calls with the rust bridge code using `block_on`.
I know the state of that fork is very confusing, sorry; I intended to clean it up a bit more before publicizing and I will try to find some time in the next couple of day to do that.
I originally had the goal of preserving the old bindings and marking them as deprecated, but with this new repo I'm not sure there's much point in that.
