The Spark Notebook allows performing reproducible analysis with Scala, Apache Spark and the Big Data ecosystem.
Apache Spark is available out of the box, and is simply accessed by the variable
Multiple Spark Context Support
One of the top most useful feature brought by the Spark Notebook is its separation of the running notebooks. Each started notebook will spawn a new JVM with its own SparkSession instance. This allows a maximal flexibility for:
- dependencies without clashes
- access different clusters
- tune differently each notebook
- external scheduling (on the roadmap)
We achieve maximum flexibility with the availability of multiple
sparkContexts by enabling metadata driven configuration.
The Spark Notebook supports exclusively the Scala programming language, the Unpredicted Lingua Franca for Data Science and extensibly exploits the JVM ecosystem of libraries to drive an smooth evolution of data-driven software from exploration to production.
The Spark Notebook is available for *NIX and Windows systems in easy to use ZIP/TAR, Docker and DEB packages.
All components in the Spark Notebook are dynamic and reactive.
The Spark Notebook comes with dynamic charts and most (if not all) components can be listened for and can react to events. This is very helpful in many cases, for example:
- data entering the system live at runtime
- visually plots of events
- multiple interconnected visual components Dynamic and reactive components mean that you don't have write the html, js, server code just for basic use cases.

Spark Notebook gives us a clean, useful way to mix code and prose when we demo and explain our tech to customers. The Spark ecosystem needed this.
It allows our analysts and developers (15+ users) to run ad-hoc queries, to perform complex data analysis and data visualisations, prototype machine learning pipelines. In addition, we use it to power our BI dashboards.
