Release 0.182#


  • Fix correctness issue that causes corr() to return positive numbers for inverse correlations.

  • Fix the EXPLAIN query plan for tables that are partitioned on TIMESTAMP or DATE columns.

  • Fix query failure when using certain window functions that take arrays or maps as arguments (e.g., approx_percentile()).

  • Implement subtraction for all TIME and TIMESTAMP types.

  • Improve planning performance for queries that join multiple tables with a large number columns.

  • Improve the performance of joins with only non-equality conditions by using a nested loops join instead of a hash join.

  • Improve the performance of casting from JSON to ARRAY or MAP types.

  • Add a new IPADDRESS type to represent IP addresses.

  • Add to_milliseconds() function to convert intervals (day to second) to milliseconds.

  • Add support for column aliases in CREATE TABLE AS statements.

  • Add a config option to reject queries during cluster initialization. Queries are rejected if the active worker count is less than the query-manager.initialization-required-workers property while the coordinator has been running for less than query-manager.initialization-timeout.

  • Add TPCDS connector. This connector provides a set of schemas to support the TPC Benchmark™ DS (TPC-DS).


  • Fix an issue that would sometimes prevent queries from being cancelled when exiting from the pager.


  • Fix reading decimal values in the optimized Parquet reader when they are backed by the int32 or int64 types.

  • Add a new experimental ORC writer implementation optimized for Presto. We have some upcoming improvements, so we recommend waiting a few releases before using this in production. The new writer can be enabled with the hive.orc.optimized-writer.enabled configuration property or with the orc_optimized_writer_enabled session property.
