Subject [jira] [Commented] (CASSANDRA-6807) Thrift with CQL3 doesn't return key
Date Thu, 06 Mar 2014 16:58:44 GMT


Peter commented on CASSANDRA-6807:

Just to make sure I don't mis-interpret again. The impression I got from Jonathan's response
is that CqlRow.key is always null and was a "special case" in the past. In other words it
is deprecated going forward.

The change with CQL3 is that KEY is just another column, so thrift does get the column. I
can live with that and will give it a try. Reading the source code, it wasn't at all obvious,
which is why I asked. I will add a comment and javadoc to ResultSet and submit a patch. Atleast
that way, if anyone else writing drivers looks they can see the explanation and ask the same
question again.

thanks for taking time to clarify.

> I'm working on adding support for CQL3 to Hector and came across an odd issue. I explicitly
include the key in the statement, but the key isn't returned. I've attached a screenshot.
Hector's CqlQuery class is doing the following to issue the cql3 call. I'm hoping it's a simple
configuration detail I'm missing or parameter I need to set.

that would tell me how to tell Cassandra to return the key in the CqlResult or CqlRow. The
queries I tried look like this
