This PR adds the
sort_byparameter to therewrite_manifestsstored procedure, exposing thesortByfunctionalitythat was added to
RewriteManifestsSparkAction. Currently, custom manifest clustering by partition fieldsis only accessible through the Java API. This change allows SQL users to specify which partition fields to cluster
manifests by, which can reduce scan planning time by enabling Spark to skip manifests that don't contain relevant
partition values.
Example:
CALL catalog.system.rewrite_manifests(table => 'db.sample', sort_by => array('category'));
