[jira] [Updated] (CASSANDRA-17198) Allow to filter using LIKE predicates
[ https://issues.apache.org/jira/browse/CASSANDRA-17198?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Benjamin Lerer updated CASSANDRA-17198:
---------------------------------------
Description:
{{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}}.
