Data aggregation pipeline for running real-time predictive models

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 Data Transform Configuration (DTC).

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

This looks like any other ETL pipeline. At this point, Blurr doesn't do anything special that you cannot do with Spark, for instance. Blurr shines when an offline model pipeline needs to be turned into an online scoring pipeline.

Blurr is MLOps

Blurr is a collection of components built for MLOps, the Blurr Core library is one of them. Blurr Core ⊆ Blurr

We believe in a world where everyone is a data engineer. Or a data scientist. Or an ML engineer. The lines are blurred (cough). Just like development and operations became DevOps over time

We see a future where MLOps means teams putting together various technologies to suit their needs. For production ML applications, the speed of experimentation and iterations is the difference between success and failure. The DTC helps teams iterate on features faster. The vision for Blurr is to build MLOps components to help ML teams experiment at high speed.

Coming up with features is difficult, time-consuming, requires expert knowledge. 'Applied machine learning' is basically feature engineering --- Andrew Ng

Use Blurr

We interact with Blurr using a Command Line Interface (CLI). Blurr is installed via pip:

$ pip install blurr

Transform data

$ blurr transform \
     --streaming-dtc ./dtcs/sessionize-dtc.yml \
     --window-dtc ./dtcs/windowing-dtc.yml \
     --source file://path

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? We'd love to know!

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
