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.
> Allow indexes for comparisons other than equal
