What is Blurr?

Blurr transforms structured, streaming raw data into features for model training and prediction using a high-level expressive YAML-based language called the Blurr Transform Spec (BTS). The BTS merges the schema and computation model for data processing.

The BTS is a data transform definition for structured data. The BTS encapsulates the business logic of data transforms and Blurr orchestrates the execution of data transforms. Blurr is runner-agnostic, so BTSs can be run by event processors such as Spark, Spark Streaming or Flink.

Is Blurr for you?

Yes, if: you are well on your way on the ML 'curve of enlightenment', and are thinking about how to do online scoring

Data Science 'Joel Test'

Inspired by the (old school) Joel Test to rate software teams, here's our version for data science teams. What's your score?

  1. Data pipelines are versioned and reproducible
  2. Pipelines (re)build in one step
  3. Deploying to production needs minimal engineering help
  4. Successful ML is a long game. You play it like it is
  5. Kaizen. Experimentation and iterations are a way of life
