> Key: DRILL-5065
> URL: https://issues.apache.org/jira/browse/DRILL-5065
> Project: Apache Drill
> Issue Type: Improvement
> Components: Storage - MapRDB
> Affects Versions: 1.9.0
> Environment: Clusters with MapR v5.2.0 and above
> Reporter: Abhishek Girish
> Assignee: Smidth Panchamia
>
> The JSON FileReader optimizes count(* ) queries, by only counting the number
> of records in the files and discarding the data. This makes the query
> execution faster & efficient.
> We need a similar feature in the MapR format plugin (maprdb) to optimize _id
> only projection & count(* ) queries on MapR-DB JSON Tables.
