Better validator support for composite comparator CFs
-----------------------------------------------------
Key: CASSANDRA-4084
URL: https://issues.apache.org/jira/browse/CASSANDRA-4084
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Tyler Hobbs
Perhaps this should be part of replacing super columns with composites, but we
essentially need something analogous to sub-column validators for when
composites are used in a way that's similar to super columns (multiple fields
for each "super column" in a row). As an example use case, suppose you have a
wide row holding users where the comparator is (<user_id>, <field>), and
<field> might be either "name" or "age"; ideally, you can validate "name" as
UT8Type and "age" as IntegerType.
Allowing wildcards to be used for components in the column name portion of the
ColumnDef might be a reasonable approach.
