    Description

      Similarly to https://issues.apache.org/jira/browse/IMPALA-9633 DataSketches Theta also has union functionality.

      ds_theta_union() expects a dataset of STRINGs (e.g. column of a table) that represents serialized Theta sketches and returns a single STRING that is the received sketches unioned and serialized.
