## What it is
An open-source web-based notebook for interactive and reactive data science using Scala and Apache Spark. It combines Scala code, SQL, markup, and dynamic charts in a collaborative editor aimed at enterprise big-data exploration.

## Use cases
- explore large datasets interactively with scala and spark
- run reproducible big data analysis in a notebook
- visualize spark data with dynamic reactive charts
- run isolated spark sessions per notebook
- analyze streaming data live in a notebook

## When to choose
- your team works in Scala on Apache Spark and wants a notebook experience
- you need per-notebook isolated Spark contexts and metadata-driven configuration
- you want reactive, live-updating visualizations over big data

## When to avoid
- you prefer Python or R notebooks like Jupyter or Zeppelin
- you need a lightweight notebook without Spark/JVM overhead
- you need a project with frequent recent releases

## Facets
- artifact type: application
- maturity: maintenance
- function: data-visualization, developer-tools, gui
- domain: data-science, big-data, data-visualization, analytics
- platform: windows, jvm
- tags: apache-spark, notebook, scala, interactive-analysis, big-data, reactive-notebooks, linux, macos, docker, web-server
