+ In place of `start` and `finish`, you may use `start_token` and
+ `end_token` or a combination of `start` and `end_token`. In this
+ case, you are specifying a token range to fetch instead of a key
+ range. This can be useful for fetching all data owned
+ by a node or for parallelizing a full data set scan. Otherwise,
+ you should typically just use `start` and `finish`.

returned. If left as ``None``, the number of rows that may be returned
is unlimted (this is the default).
