Alex Petrov commented on CASSANDRA-10624:
-----------------------------------------
I've added support for UDTs in CQLSStableWriter. The main problem here was to
make a syntax that would allow user to create user defined types without
needing to touch {{ByteBuffer}} directly, which is now done through the
mechanisms similar to {{UDFs}}.
In order to get a {{UDT
It's probably also worth mentioning
https://datastax-oss.atlassian.net/browse/JAVA-502, as there's a comment since
Dec 2014 in {{UDHelper}}, although the issue itself is closed with wontfix.
> 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
> Assignee: Alex Petrov
> 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).
