Paul Rogers commented on DRILL-7458:
------------------------------------
This ticket is paused. The general idea is still valid, but the simple solution
proposed in the PR was perhaps a bit too simple. There is another set of
tickets about improving the storage plugin mechanism itself, and work was
started on that. These efforts should be combined to create a "version 2" of
the storage plugin mechanism that is a bit easier to implement, easier to
test, and easier to install, version and so on.

> The "Easy" framework allows third-parties to add format plugins to Drill with
> moderate effort. (The process could be easier, but "Easy" makes it as simple
> as possible given the current structure.)
> At present, no such "starter" framework exists for storage plugins. Further,
> multiple storage plugins have implemented filter push down, seemingly by
> copying large blocks of code.
> This ticket offers a "base" framework for storage plugins and for filter
> push-downs. The framework builds on the EVF, allowing plugins to also support
> project push down.
> The framework has a "test mule" storage plugin to verify functionality, and
> was used as the basis of an REST-like plugin.
