Today I'm happy to announce the availability of the Drill 1.1 release. This release addresses 162 JIRAs on top of May's 1.0 release. Highlights include:
Automatic Partitioning for Parquet Files
Drill now supports creating partitions automatically when using
CREATE TABLE AS (CTAS) to generate Parquet files. By leveraging the unique capabilities of the Parquet file format, Drill is able provide this capability and still maintain data integrity and compatibility with all other systems that consume Parquet (a world's first). This functionality can be exercised by utilizing the new
PARTITION BY clause support.
Drill now has first-class support for SQL window Functions. This includes:
- Aggregate Functions:
- Ranking Functions:
The community has done an excellent job providing a comprehensive documentation so that you can start using window functions immediately.
Hive Storage Plugin Enhancements
We've enhanced Drill to work even better with Hive. We started by upgrading Drill's support to work with Hive 1.0. In addition, Drill now provides a powerful new security feature called delegated Hive impersonation. Compatibility and performance are also improved with better data type support (including support for binary, tinyint and smallint data types) and better concurrency.
SQL UNION Improvements
We've enhanced support for SQL
UNION functionality. Drill now supports both
UNION ALL capabilities. We've also improved the query optimizer to better optimize plans that include the
New Features For Complex Data
Drill's complex data capabilities continue to be the best in the market, now including support for
COUNT aggregations on various types of complex objects. Also, Drill's
FLATTEN function now supports very large complex objects.
Improved JDBC Driver Compatibility
The Apache Drill community now publishes the JDBC driver for easy inclusion in your application through the use of Maven coordinates. You can incorporate Drill's JDBC driver into your application by downloading it directly or referencing the following coordinates within your Maven application.
