Cassandra Limitations
If running a standard selection rule against a Cassandra auxiliary database, a number of features are not supported:
Compare to attribute criteria
Nested and multiple criteria lists using cross-resolution levels
Functions
Joins
Exclude
OR
Full text string search
If you attempt to run a standard selection rule that contains one or more of the features listed above, a warning is displayed.
In addition, a warning is displayed when running a selection rule containing filter criteria when filtering has not been enabled and indexes not applied at the columns thus utilized within a Cassandra database.
