-------------------------------------------
Summary: Prepared marker for collections inside UDT are not
properly handled
Key: CASSANDRA-7472
URL: https://issues.apache.org/jira/browse/CASSANDRA-7472
Project: Cassandra
Issue Type: Bug
Reporter: Sylvain Lebresne
Assignee: Sylvain Lebresne
Fix For: 2.1.0
Collections inside UDT needs to be encoded with the v3 protocol. However, we
allow to prepare queries like:
{noformat}
INSERT INTO foo (k, v) VALUES (0, { s: ? });
{noformat}
In that case, if {{s}} is a collection, a client driver will only know that a
collection is expected for that prepared variable, but it will have no way to
know for sure that this collection is really part of a UDTValue. So we should
handle this server side (i.e. let the user send the collection encoded with the
protocol v2, but re-encode it properly).
