paul-rogers opened a new pull request #1914: DRILL-7458: Base framework for storage plugins
URL: https://github.com/apache/drill/pull/1914
 
 
   Drill has an increasing number of storage plugins.
   It turns out, many have the same boilerplate code
   copy and pasted into each new plugin. This patch
   provides a generic framework to allow easier creation
   of storage plugins by abstracting out the
   boilerplate.
   
   Many storage plugins provide filter push-down,
   again by copying a large amount of boilerplate
   code from earlier plugins. This patch provides a
   generic filter push-down framework that abstracts out
   the common Drill/Calcite work, allowing the plugin
   to implement just the functionality unique to that
   plugin.
   
   A "dummy" plugin shows how to use both frameworks and
   acts as a "test mule" for the filter push-down framework.
