Dispatch SDK v0.7.0

Dispatch SDK v0.6.0

Python SDK v0.6.0 was released.

Terminal window
pip install dispatch-py==0.6.0

This version brings a lot of new and powerful APIs to the SDK.

The main change that v0.6 brings is enabling the integration of Dispatch in applications that are not based on FastAPI. The top-level dispatch package can now be used to create vanilla Dispatch applications:

import dispatch
# The .function decorator is available on the top-level package to
# declare functions that can be orchestrated by the scheduler.
def greet(who: str): ...
# The .run function runs the main event loop interacting with the
# scheduler. It takes an optional initialization function that will
# be called right before entering the event loop. greet.dispatch("me"))

New features


  • Don’t print verification key warning when running under Dispatch CLI by @chriso in #152
  • Extract new proto fields by @chriso in #153

Dispatch SDK v0.5.1

Python SDK v0.5.1 of the Python SDK was released.

Terminal window
pip install dispatch-py==0.5.1

This version adds multiple bug fixes, including one that prevented dispatch functions from running concurrently within a single application instance (distributing concurrent calls across multiple instances was unaffected).


  • Run Dispatch functions in a thread executor by @chriso in #146
  • Add experimental Lambda integration by @Pryz in #142

Bug fixes

  • Don’t pickle coroutine state twice by @chriso in #148

April 2, 2024

Dispatch SDK v0.5.0

Python SDK v0.5.0 was released.

Terminal window

Dispatch SDK v0.4.2

Python SDK v0.4.2 was released.

Terminal window
pip install dispatch-py==0.4.2

With this patch release, programs that run on Python 3.8 can now use Dispatch.


Full changelog: v0.4.1...v0.4.2

March 26, 2024

Python SDK v0.4.1 was released.

Terminal window
pip install dispatch-py==0.4.1

This patch release brings compatibility with Python 3.9 and 3.10. Prior to this update, the Python SDK for Dispatch was only compatible with Python 3.11+, which caused a lot of issues due to default Python installations often being older on OSX and Ubuntu (usually 3.9). This caused a lot of friction for users who tried Dispatch but didn’t have a supported version pre-installed.

March 26, 2024

Dispatch SDK v0.4.0

Python SDK v0.4.0 was released.

Terminal window
pip install dispatch-py==0.4.0

This is an important release with new concurrency APIs to compose more advanced applications powered by Dispatch. The release also includes new default integrations for errors raised by popular services like Slack and OpenAI, so dispatch functions can automatically handle retries when executing requests to those APIs.

New features

Bug fixes

  • Fix registration of synchronous functions by @chriso in #129

Full changelog: v0.3.0...v0.4.0

March 18, 2024

Dispatch SDK v0.3.0

Python SDK v0.3.0 was released.

Terminal window
pip install dispatch-py==0.3.0

SDK v0.3.0 introduces a new feature: dispatch.batch. With batch, you can construct batches of functions to be dispatched and executed concurrently. This new feature is perfect if you are building things like a data pipeline where you will want to process multiple chunks of data at once to increase your system throughput.

from dispatch import batch
def funcA(): ...
def funcB(someargs): ...
batch = dispatch.batch()
batch.add(funcB, someargs)

New features


  • Improve UX around verification keys by @chriso in #120


  • Add section describing serialization and its quirks by @chriso in #118
