Abhishek Girish created DRILL-5065: -------------------------------------- Summary: Optimize count( *) queries on MapR-DB JSON Tables 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
