12.131. Release 0.126
General Changes
- Add error location information (line and column number) for semantic errors.
- Fix a CLI crash during tab-completion when no schema is currently selected.
- Fix reset of session properties in CLI when running USE.
- Fix occasional query planning failure due to a bug in the projection
push down optimizer.
- Fix a parsing issue when expressions contain the form
POSITION(x in (y)).
- Add a new version of
approx_percentile() that takes an accuracy
parameter.
- Allow specifying columns names in INSERT queries.
- Add
field_length table property to blackhole connector to control the
size of generated VARCHAR and VARBINARY fields.
- Bundle Teradata functions plugin in server package.
- Improve handling of physical properties which can increase performance for
queries involving window functions.
- Add ability to control whether index join lookups and caching are shared
within a task. This allows us to optimize for index cache hits or for more
CPU parallelism. This option is toggled by the
task.share-index-loading
config property or the task_share_index_loading session property.
- Add Tableau web connector.
- Improve performance of queries that use an
IN expression with a large
list of constant values.
- Enable connector predicate push down for all comparable and equatable types.
- Fix query planning failure when using certain operations such as
GROUP BY,
DISTINCT, etc. on the output columns of UNNEST.
- In
ExchangeClient set maxResponseSize to be slightly smaller than
the configured value. This reduces the possibility of encountering
PageTooLargeException.
- Fix memory leak in coordinator.
- Add validation for names of table properties.
Hive Changes
- Fix reading structural types containing nulls in Parquet.
- Fix writing DATE type when timezone offset is negative. Previous versions
would write the wrong date (off by one day).
- Fix an issue where
VARCHAR columns added to an existing table could not be
queried.
- Fix over-creation of initial splits.
- Fix
hive.immutable-partitions config property to also apply to
unpartitioned tables.
- Allow non-
VARCHAR columns in DELETE query.
- Support
DATE columns as partition columns in parquet tables.
- Improve error message for cases where partition columns are also table columns.
