Extracted Release Notes

• Add use-exact-partitioning-enabled session property #13354 (Author: Ariel Weisberg): Add use-exact-partitioning-enabled session property
  • Add use_exact_partitioning session property that forces repartitioning if repartitioning is possible.
• Support retries of streaming sections #13717 (Author: Rebecca Schlussel): Support retries of streaming sections
  • Add support for retrying failed stages from a materialized point instead of failing the entire query. The number of retries allowed can be configured using the configuration property max-stage-retries and session property max_stage_retries. The default value is zero. To take advantage of this feature, exchange_materialization_strategy must be set to 'ALL'.
  • Add configuration property use-legacy-scheduler and session property use_legacy_scheduler to use a version of the query scheduler from before refactorings to enable full stage retries. The default value is false. This is a temporary property to provide an easy way to roll back in case of bugs in the new scheduler. This property will be removed in a couple releases once we have confidence in the stability of the new scheduler.
• Support ALTER FUNCTION #13799 (Author: Leiqing Cai): Support ALTER FUNCTION
  • Add support for ALTER FUNCTION.
• Support internal communication with thrift #13894 (Author: James Sun): Support internal communication with thrift
  • Allow Presto nodes to shuffle data with Thrift protocol. Use config internal-communication.task-communication-protocol to control between HTTP and Thrift.
  • Allow Presto nodes to announce state with Thrift protocol. Use config internal-communication.server-info-communication-protocol to control between HTTP and Thrift.
• Configure DB Resource Group reload frequency #13931 (Author: Swapnil Tailor): Configure DB Resource Group reload frequency
  • Making database resource group reload frequency configurable.
  • ...
• Update error code when table is dropped during query execution #13934 (Author: Vic Zhang): Update error code when table is dropped during query execution
  • When DROP TABLE query fails because the table has being dropped by other query before this query finishes, change error code name from HIVE_METASTORE_ERROR to HIVE_TABLE_DROPPED_DURING_QUERY.
• Add t-digest functions to Presto #13940 (Author: Timothy Meehan): Add t-digest functions to Presto
  • Add tdigest_agg, merge(tdigest), value_at_quantile(tdigest, quantile), values_at_quantiles(tdigest, quantiles), quantile_at_value(tdigest, quantile), quantiles_at_values(tdigest, quantile) for creating, merging, and querying t-digests.
  • IsHidden attribute on AggregationFunction and ScalarFunction removed and replaced with visibility.
• Enable listing SQL function with session property #13949 (Author: Leiqing Cai): Enable listing SQL function with session property
  • Support hiding user-defined SQL functions in SHOW FUNCTIONS with session property list_built_in_functions_only. This can also be achieved by configuration property list-built-in-functions-only, which is repurposed from list-non-built-in-functions.
• Support MySQL-based FunctionNamespaceManager #13972 (Author: Leiqing Cai): Support MySQL-based FunctionNamespaceManager
  • Add a MySQL-based function namespace manager implementation that supports creating, altering, and dropping SQL functions. (:doc:/admin/function-namespace-managers).

  • Add support to show whether functions have variable arity in SHOW FUNCTIONS.
  • Add support to show whether functions are built-in in SHOW FUNCTIONS.
• Cache builtin function resolution result #13982 (Author: Rongrong Zhong): Cache builtin function resolution result
  • Improve built-in function resolution performance by caching function resolution results.
• Improve correctness check for queries that produce columns of RowType #13998 (Author: Igor Kruk): Improve correctness check for queries that produce columns of RowType
  • Add checks for the individual fields when validating a row column.
• Support shuffle on Hive partition columns before write #14010 (Author: Wenlei Xie): Support shuffle on Hive partition columns before write
  • Allow shuffle on partitioned columns when writing to partitioned unbucketed Hive tables. This increase the number of maximum partitions written in single query by a factor of number of total writing workers.This behavior has to be explicitly enabled by Connector session property shuffle_partitioned_columns_for_table_write. Support shuffle on Hive partition columns before write #14010.
• Upgrade slice to 0.38 #14014 (Author: James Gill): Upgrade slice to 0.38
  • Upgrade airlift/slice to 0.38.
• Add task memory related session properties  #14016 (Author: Ariel Weisberg): Add task memory related session properties
