This document summarizes the agenda for a Zeppelin Meetup. The agenda includes demos of real-time streaming and running Zeppelin on Kubernetes, as well as discussing the Zeppelin roadmap and taking questions. The roadmap focuses on modernizing the front-end, adding collaboration features, running applications alongside notebooks on Kubernetes, and improving visualization capabilities.

Benefits
MULTI-TENANCY
Each note and/or user has own
container for interpreters
SCALABILITY
Single host does not run all
interpreters anymore
SECURITY
Each container is isolated
(filesystem, process etc.)

Usage
$ kubectl apply -f ${ZEPPELIN_HOME}/k8s/zeppelin-server.yaml
* Need to build your own Zeppelin and Spark docker image before 0.9.0 is released
1. Build Zeppelin distribution package mvn package -Pbuild-distr …
2. Build Zeppelin docker image cd scripts/docker/zeppelin/bin; docker build -t …
3. Build Spark docker image <spark-distribution>/bin/docker-image-tool.sh -m -t 2.4.0 build
Available in 0.9.0-SNAPSHOT

Zeppelin Roadmap
- Zeppelin on Kubernetes
- Apply network policy to isolate Interpreter Pod
- Schedule note on background as a Job in Kubernetes
- Run extra application such as terminal, tensorboard, the sameway SparkUI works
- Modernize front-end stack
- Currently AngularJS
- Dark theme?
- Visualization
- Realtime data visualization
- Pivot in the backend side, instead of doing it in a front-end that require transfer all data to front-end
- Sidebar
- Sidebar with widgets, such as ToC (Table of Contents, list of data, etc)
- Online widget registry (Helium)
- Collaboration
- Multi-cursor edit
- Comment!

Problem
- Entire result dataset need to be transferred to browser, even though not all of
them are rendered.
- Browser CPU, memory is limitation of transforming / rendering data
