python module wrapper for the data analytics software framework DASF

Abstract

DASF: Messaging Python is part of the Data Analytics Software Framework (DASF, https://codebase.helmholtz.cloud/dasf), developed at the GFZ German Research Centre for Geosciences (https://www.gfz-potsdam.de). It is funded by the Initiative and Networking Fund of the Helmholtz Association through the Digital Earth project (https://www.digitalearth-hgf.de/).

DASF: Messaging Python is a RPC (remote procedure call) wrapper library for the python programming language. As part of the data analytics software framework DASF, it implements the DASF RPC messaging protocol. This message broker based RPC implementation supports the integration of algorithms and methods implemented in python in a distributed environment. It utilizes pydantic (https://pydantic-docs.helpmanual.io/) for data and model validation using python type annotations. DASF distributes messages via a central message broker. Currently we support a self-developed message broker called dasf-broker-django, as well as an ‘off-the-shelf’ solution called Apache Pulsar. (also see: Message Broker)
