January 13, 2016


Apache Drill 1.4 is now available on MapR. This is a production ready and supported release on MapR and highly recommended for all customer deployments.


Drill 1.4 is a performance and stability focused release. The key enhancements in the release include the following.

  • Improved and optimized Tableau experience with faster Limit 0 queries
  • Metadata (INFORMATION_SCHEMA) query speed-ups on Hive schemas/tables
  • Optimized query planning and execution through enhanced partition pruning
  • Efficient caching of Parquet metadata, speeding up queries on large numbers of files
  • Improved window functions, resource usage, and performance
  • Table functions

  • New and improved MapR Drill JDBC driver


Note: There is one backwards incompatible change when using Drills CTAS with partitioning. You must update the metadata of Parquet files generated by the prior versions of Drill (1.2 and before) to work optimally with Drill version 1.4. See and DRILL-4070
