To enjoy access to TileDB arrays registered with TileDB Cloud, you do not need an extra client. You can continue to use your favorite TileDB Developer API or integration, tweak a couple of parameters and you are all set. See Array Access for details.

You can install the latest release of TileDB-Cloud-Py as follows:
pip install tiledb-cloud
The latest development version of TileDB-Cloud-Py can be installed directly from Github:
