21.99. Release 0.133

General Changes

  • Add support for calling connector-defined procedures using CALL.
  • Add System Connector procedure for killing running queries.
  • Properly expire idle transactions that consist of just the start transaction statement and nothing else.
  • Fix possible deadlock in worker communication when task restart is detected.
  • Performance improvements for aggregations on dictionary encoded data. This optimization is turned off by default. It can be configured via the optimizer.dictionary-aggregation config property or the dictionary_aggregation session property.
  • Fix race which could cause queries to fail when using concat() on ARRAY, or when enabling columnar_processing_dictionary.
  • Add sticky headers and the ability to sort the tasks table on the query page in the web interface.
