Crunch allows you to stream data to a dataset. Streaming data is useful for
datasets which have frequent updates (see the
Crunch API documentation for more
information). Crunch automatically appends streamed data periodically;
however, if you would like to trigger appending pending streamed data to a
dataset, you can use appendStream()
.
appendStream(ds)
a CrunchDataset
the dataset with pending stream data appended.
