Release 0.246#

Details#

General Changes#

  • Fix a bug introduced in #15313 that would cause queries to fail when using upper case in SQL function catalog schema names.

  • Fix a possible integer overflow error when spilling to temporary storage.

  • Fix an issue where prepared statements would allow some non-constant parameters.

  • Fix an error where Presto server can fail to start when using function namespace manager.

  • Add a minimum value of 30 seconds to the configuration property query.min-expire-age.

  • Add listener-based revocation model for spilling strategy PER_TASK_MEMORY_THRESHOLD.

  • Disable spill to disk for join queries where the probe side uses grouped execution and the build does not. Previously these queries would fail with GENERIC_INTERNAL_ERRORS.

  • Disallow ORDER BY literals used with Window functions as it’s not useful, expensive and most often used wrongly.

  • Add support for fragment result caching for queries with local exchange (e.g. intermediate aggregation).

  • Improve queries that have unnecessary limits and order bys. This feature is enabled by default and can be disabled by using the configuration property optimizer.skip-redundant-sort or session property skip_redundant_sort.

Geospatial Changes#

  • Upgrade JTS to 1.18.0.

Hive Changes#

  • Fix dynamic pruning failures for joining on null keys in hive partition.
