Dapr SDK for Python

Dapr is a portable, event-driven, serverless runtime for building distributed applications across cloud and edge.

Dapr SDK for Python allows you to implement the Virtual Actor model, based on the actor design pattern. This SDK can run locally, in a container and in any distributed systems environment.

This includes the following packages:

• dapr.actor: Actor Framework
• dapr.clients: Dapr clients for Dapr building blocks
• dapr.conf: Configuration
• dapr.serializers: serializer/deserializer
• dapr.proto: Dapr gRPC autogenerated gRPC clients
• flask_dapr: flask extension for Dapr

Status

Note: Dapr SDK for python is currently under community development in alpha phase.
