 Caterva2 offers the possibility of using the publisher-subscriber (pub-sub) message pattern. Under this framework, when a user uses a client (Web API, Python API or command line) to query datasets, the client will connect to a Caterva2 **subscriber** service, which in turn will communicate with the associated **publishers** to which it is subscribed, to retrieve the requested datasets. This subscriber/publisher interaction is mediated by a **broker** service.

 accesses the relevant datasets stored either locally or remotely. The subscriber services may be managed via the command line by installing the `caterva2` package with the `[subscriber]` extra feature (we also wish to use the command line client, so we will also install the `clients` extra too):
