cgivre opened a new pull request #1892: Drill-7437: Storage Plugin for Generic 
HTTP REST API
URL: https://github.com/apache/drill/pull/1892
 
 
   In many data analytic situations there is a need to obtain reference data 
which is volatile or hosted on a service with a REST API.  
   
   For instance, consider the case of a financial dataset which you want to run 
a currency conversion.  Or in the security arena, an organization might have a 
service that returns network information about an IT asset.  The goal being to 
enable Drill to quickly incorporate external data that is only accessible via 
REST API. 
   
   This plugin is not intended to be a substitute for dedicated storage plugins 
with systems that use a REST API, such as Apache Solr or ElasticSearch.  
   This plugin is based on several projects that were posted on github but 
never completed or submitted to Drill.  Posted here for attribution:

   ## Usage
   To configure the plugin, create a new storage plugin, and add the following 
configuration options:
   
   ```
   {
     "type": "http",
     "connection": "https://api.sunrise-sunset.org/";,
     "resultKey": "results",
     "enabled": true
   }
   ```
   The options are:
   * `type`:  This should be `http`
   * `connection`:  This should be the root level URL for your API.
   * `resultKey`:  The result key is the key in the results which contains a 
table-like structure of the data you want to retrieve.  Using this will help 
you eliminate other data
    that often is transmitted in API calls. 
   
   
   ### Sample:
   ```
   SELECT sunrise, sunset
   FROM api.`/json?lat=36.7201600&lng=-4.4203400&date=today`;
   ```
