Note: CASSANDRA-19837 is a dupe of this ticket

We haven’t been converting old JAVA tickets to CASSANDRA tickets but we have been opening all new tickets as CASSANDRA tickets (or at least trying to; I think one or two might have slipped past). Since we already had a JAVA ticket to reflect this work it seemed to make the most sense to just leave it here.

Can this now be a CASSANDRA ticket ?

”If I have a query that returns a vector I should get a CqlVector type back when I execute it”
Right now the following works, is this enough?

ResultSet rs = session.execute(SimpleStatement.newInstance("select query_vector_value from movie_reviews limit 1;")); Object vector = rs.one().getVector("query_vector_value", Float.class); System.out.println(vector); // [0.1, 0.2] System.out.println(vector.getClass().getName()); // CqlVector

This means sth like this should work:

selectFrom("sensor_data")

.column("reading")

.whereColumn("id").isEqualTo(bindMarker())
.orderBy(Ann.of(“item_vector”, new CqlVector(Arrays.asList(0.1, 0.1)))
