Regarding JPQL, that's expected, as there is no parser implementation which would take JPQL and convert it to CQL (we have an implementation though which converts JPQL into Lucene queries executed via Hibernate Search, so that might be an alternative).

But it should work with native queries, see this test in the test suite: CassandraEntityManagerNativeQueryTest. I'm wondering, whether it actually is related to usage via Spring (haven't tried that myself in a long time).

Any chance you provide a simple reproducer (smallest possible Maven project exposing the issue), so we can take a look?
