Announcing the 0.0.3 release of riff

January 26, 2018

We are excited to announce a shiny new release of riff. Thank you, all the riff team and community members who contributed to make this happen.

Highlights of the 0.0.3 release include the following:

  • Ported the function controller to go.

  • A much improved riff command line script, supporting the following commands.

      init         Initialize a function
  build        Build a function container
  apply        Apply function resource definitions
  create       Create function resources, build container and apply the function resources
  update       Build the container and apply the modified function resources
  delete       Delete function resources
  list         List current function resources
  logs         Show logs for a function resource
  publish      Publish data to a topic using the http-gateway
  version      Display the riff version

    riff init will generate a new Dockerfile as well as yaml files for Function and Topic resource defintions. riff create is a combination of riff init and riff build and riff apply.

  • Windows support for the same commands via a new riff.bat.

  • JavaScript async or promised functions can now be used in addition to synchronous functions.

    // sync
module.exports = name => `Hello ${name}!`;

// promise
module.exports = name => Promise.resolve(`Hello ${name}!`);

// async
module.exports = async name => `Hello ${name}!`;

  • A quicker cold start for the java function invoker.

  • Improved message headers and gRPC support.

Roadmap

Work planned for upcoming iterations includes:

  • Contract between the sidecar and function containers
  • Emit event metrics from the sidecar
  • Improve function scaling based on published metrics
  • JavaScript streaming
  • Functions for event sources
