workflows 2.20

Data processing in distributed environments

Workflows enables light-weight services to process tasks in a message-oriented environment.

It is comprised of a communications layer (workflows.transport) that provides a common interface to queues and topics over different transport providers, a service abstraction layer (workflows.frontend) which encapsulates a service in a separate process, tools for status reporting, logging and controlling services via a transport mechanism, and a service class skeleton alongside example services (workflows.services.common_service et al.). To achieve more complex workflows services can be interconnected using recipes whereby the output of one service can be directed onwards to other services.
