Zeppelin Singularity 🎈

A limited, single-node deployment of Apache Zeppelin notebooks for Apache Spark and PostgreSQL.

This app layers zeppelin-in-space on spark-singularity to support limited, proof-of-concept experimentation using a single Heroku dyno in the Common Runtime.


A few important notes 🌻

  • Performance-L dyno is required to avoid memory errors
    • true big-data capabilities require a Spark cluster
    • this single-instance deployment is suited for collaborative exploration & learning
  • the settings found in Zeppelin UI: Interpreter, Credential, & Configuration are read only
