Berenguer Blasi commented on CASSANDRA-17198:
---------------------------------------------
Hi [~subkanthi],
the code you have so far is great. But as you can see in the CI run above some
of the tests failed because the behavior for the {{LIKE}} operator has changed.
Those tests need to be amended to the new behavior. Please notice trunk has
[currently|https://ci-cassandra.apache.org/job/Cassandra-trunk/] some failures.
So you can check current failures vs your branch failures and you should only
fix those tests failing because of the changes to {{LIKE}}. Makes sense? Let me
know any questions please.
> Allow to filter using LIKE predicates

> Key: CASSANDRA-17198
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17198
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL/Syntax
> Reporter: Benjamin Lerer
> Assignee: Kanthi Subramanian
> Priority: Normal
> Labels: AdventCalendar2021, lhf
> Fix For: 4.x
>
>
> {{LIKE}} predicates can only be used with the SASI indices. In several
> usecases (e.g. querying the {{settings}} virtual table) it makes sense to
> support them for filtering.
> +Additional information for newcomers:+
> There are some checks in the {{StatementRestrictions}} constructor and on
> {{LikeRestriction}} that need to be removed for allowing filtering using LIKE
> on clustering and regular columns.
> For filtering on partition columns the {{needFiltering}} methods in
> {{PartitionKeySingleRestrictionSet}} will need to be modified to return true
> when LIKE predicate are used.
> The unit tests should go in {{SelectTest}}.
