Add support for column aliases in CREATETABLEAS 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.
