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.
If you wish to enjoy the TileDB Cloud serverless capabilities and manage your shared arrays programmatically, you need to add a package called TileDB-Cloud-Py.
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:
pip install -e git+"ssh://firstname.lastname@example.org/TileDB-Inc/TileDB-Cloud-Py#egg=tiledb-cloud"
