TFX OSS roadmap

This highlights the main OSS efforts for the TFX team in 2019 and H2 2020. If you're interested in contributing in one of these areas, contributions are always welcome, especially in areas that extend TFX into infrastructure currently not widely in use at Google.

Vision

  • Democratize access to machine learning (ML) best practices, tools, and code.
  • Enable users to easily run production ML pipelines locally, on public clouds, on premises, and in heterogeneous computing environments.

Goals

  • Help enterprises realize large-scale production ML capabilities similar to what we have available at Google. We recognize that every enterprise has unique infrastructure challenges, and we want TFX to be open and adaptable to those challenges.
  • Stimulate innovation: Machine learning is a rapid, innovative field and we want TFX to help researchers and engineers both realize and contribute to that innovation. Likewise, we want TFX to be interoperable with other ML efforts in the open source community.
  • Usability: We want the experience to deploy a model in production to be as frictionless as possible throughout the entire journey -- from the initial efforts building a model to the final touches of deploying in production.

Specific efforts underway

Extensibility
  • Encourage the discovery and reuse of external contributions.
  • Participate in and extend support for other OSS efforts, initially: Apache Beam, ML Metadata, Tensorboard, and TensorFlow 2.0.
  • Make TFX more ML framework neutral to enable wider usage.
  • Extend portability across additional cluster computing frameworks and data representations.
Performance
  • Better distributed training support (DistributionStrategy).
  • Support for more performant file storage formats than TFRecords.
  • Better telemetry for users to understand the behavior of components in a TFX pipeline.
Usability
  • Support more distributed strategies in TensorFlow 2.x.
  • Improving the testing capabilities for OSS developers.
  • Reach feature parity and make it easy to move ML focused pipelines from Kubeflow pipelines (KFP) to TFX DSL. Also share the same pipeline intermediate representation for both platforms to guarantee semantics and data model consistency.
  • Support for training on continuously arriving data and more advanced orchestration semantics.
  • Create examples and templates for more ML verticals.
Education
  • Work with ML Metadata to publish standard ontology types and show case them through TFX.
Innovation and collaboration
  • Further enhance integration with tf.Lite to better support mobile and edge devices.
  • Formalize Special Interest Groups (SIGs) for specific aspects of TFX to accelerate community innovation and collaboration.
  • Early access to new features.
