GitHub user spanchamiamapr opened a pull request:
https://github.com/apache/drill/pull/667
MD-1062 - Optimize count( * ) queries on MapR-DB JSON Tables
We enabled _id only projection for JSON tables in MapR v5.2.0
Hence, removing the inefficient workaround which was getting entire document when
1. Only '_id' is projected, or
2. When the user runs a count(*) query
