Subject [jira] [Commented] (CASSANDRA-6757) SliceQueryFilter can accept multiple ColumnSlice but not exposed to thrift
Date Tue, 25 Feb 2014 02:32:19 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6757?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13911152#comment-13911152

Edward Capriolo commented on CASSANDRA-6757:
--------------------------------------------

I am sure someone is going to notice. That there is only one parameter to the method.

{code}
list<ColumnOrSuperColumn> get_multi_slice(1:required MultiSliceRequest request)
                            throws (1:InvalidRequestException ire, 2:UnavailableException
ue, 3:TimedOutException te),
{code}

I did it this way because thrift does not allow having two methods with the same name. I feel
that evolution wise it is easier to provide a single object with all optional parameters then
to deal with the issues of methods adding /removing parameters and breaking compatibility,
though I do not see this method changing much. Anyway this decision is debatable.

> Thrift has getSlice() which takes a key and a predicate. SliceQueryFilter can accept
multiple ColumnSlice(s). Users should have access to this capability already found in Cassandra.
