             Summary: Remove Deprecated JSON Reader
                 Key: DRILL-8241
                 URL: https://issues.apache.org/jira/browse/DRILL-8241
             Project: Apache Drill
          Issue Type: Improvement
          Components: Storage - JSON
    Affects Versions: 1.20.1
            Reporter: Charles Givre
             Fix For: 2.0.0


This is a master ticket to remove the deprecated v1 JSON reader from Drill.  This JSON reader is used in several places and removing it will ensure consistent behavior across all data sources. 

The V2, EVF based JSON reader has several advantages, including the possibility of schema provisioning, limit pushdowns and others.

Here are the tasks which need to be completed to fully remove the v1 JSON reader.
 * Convert the convert_fromJSON functions to V2
 * Convert the Druid Storage Plugin to V2
 * Convert MongoDB Storage Plugin to V2.  (Note the MongoDB plugin uses an EVF-based BSON reader as well as the V1 JSON reader)
 * Remove all V1-based unit tests
 * Migrate the JsonOptions from the HTTP Storage Plugin to global location to allow other plugins and users of JSON to set JSON configuration at a more granular level.
 * Remove extraneous configuration options.
