> Key: ASTERIXDB-2898
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-2898
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: IDX - Indexes
> Reporter: Glenn Justo Galvizo
> Priority: Major
>
> Scenario:
> User 1's favorite bands (array of band ids) list is B - find Users with some
> specified Jaccard similarity to User 1 (i.e., with a specified fraction of
> overlap).
> Could maybe introduce a rule to rewrite this plan into a self-join which will
> then become optimized by the introduce-join-access-method rule.
