Query Client
************

The Query Client provides functions to query Data Lab database
holdings for data (either synchroneously or asynchroneously), and to
retrieve the query results. Much of its functionality is described in
the default Data Lab `Jupyter notebook on the Query Client
<https://github.com/noaodatalab/notebooks-latest/tree/master/04_HowTos/QueryClient>`_.
