Subject [jira] [Created] (CASSANDRA-10624) Support UDT in CQLSSTableWriter
Date Fri, 30 Oct 2015 09:32:27 GMT
Sylvain Lebresne created CASSANDRA-10624:
--------------------------------------------

             Summary: Support UDT in CQLSSTableWriter
                 Key: CASSANDRA-10624
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10624
             Project: Cassandra
          Issue Type: Improvement
          Components: CQL
            Reporter: Sylvain Lebresne
             Fix For: 3.x


As far as I can tell, there is not way to use a UDT with {{CQLSSTableWriter}} since there
is no way to declare it and thus {{CQLSSTableWriter.Builder}} knows of no UDT when parsing
the {{CREATE TABLE}} statement passed.

In terms of API, I think the simplest would be to allow to pass types to the builder in the
same way we pass the table definition. So something like:
{noformat}
String type = "CREATE TYPE myKs.vertex (x int, y int, z int)";
String schema = "CREATE TABLE myKs.myTable ("
              + "  k int PRIMARY KEY,"
              + "  s set<vertex>"
              + ")";
String insert = ...;
CQLSSTableWriter writer = CQLSSTableWriter.builder()
                                          .inDirectory("path/to/directory")
                                          .withType(type)
                                          .forTable(schema)
                                          .using(insert).build();
{noformat}

I'll note that implementation wise, this might be a bit simpler after the changes of CASSANDRA-10365
(as it makes it easy to passe specific types during the preparation of the create statement).
