[jira] [Commented] (CASSANDRA-4091) multiget_slice thrift interface
always returns empty list in erlang
[ https://issues.apache.org/jira/browse/CASSANDRA-4091?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13239826#comment-13239826 ]
Jonathan Ellis commented on CASSANDRA-4091:
-------------------------------------------
multiget_slice is pretty well-tested, so I suspect there's a problem with your code.
I can't read erlang but if you can reproduce in Python maybe I could spot the problem.

> multiget_slice doesn't work in erlang and always returns an empty list, however multiget_count does for the same set of keys. Sample code:
> Keys = [<<"key1">>, <<"key2">>],
> ColumnParent = #columnParent{column_family=ColumnFamily},
> SliceRange = #sliceRange{start="", finish="", reversed=false, count=2147483647},
> SlicePredicate = #slicePredicate{slice_range=SliceRange, column_names=undefined},
> {ok, Conn} = thrift_client_util:new(Host, Port, cassandra_thrift, [{framed, true}]), ok,
> {Conn2, {ok, ok}} = thrift_client:call(Conn, set_keyspace, [Keyspace]),
> {NewCon, Response} = thrift_client:call(Conn2, multiget_slice, [Keys, ColumnParent, SlicePredicate, 1]),
> Response: {ok, []}
> Please fix.
