Subject [jira] [Commented] (CASSANDRA-3994) Allow indexes for comparisons other than equal
Date Mon, 19 Mar 2012 07:23:38 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3994?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13232490#comment-13232490

Dmitry Petrashko commented on CASSANDRA-3994:
---------------------------------------------

Please recheck it one more time.
I never mentioned that this patch is modifying get_indexed_slices.
As of current trunk get_ranged_slices uses 
ThriftValidation.validateKeyRange to validate key range in request
ThriftValidation.validateKeyRange uses ThriftValidation.validateFilterClauses (Line 507) to
validate range.row_filter

And there it is checked that at least one (expression.op != null) && indexedColumns.contains(expression.column_name);
Thus current trunk Doesnt allow queries with filters not containing EQ operations on indexed
columns.

This patch modifies validation of request in get_ranged_slices to allow requests with filters
that use indexes on operations other than EQ.

> This is also gives initial support for indexes other than KEYS
