"..including key filters ... is an expensive operation that should not be used in production"

Craig,

The warning is there to discourage users from using list-keys, but it
doesn't prevent the operation from performing. Generally, list-keys can spam
a lot of your cluster, potentially blocking other operations (until some
upcoming changes land, and always on 0.14.x). You should still plan for the
day when list-keys will be too inconvenient even for the occasional query.

Nevertheless, you can disable that warning message using:

Riak.disable_list_keys_warnings = true
