2. Who we are?

3. What is Apache Zeppelin?
A web-based notebook that enables interactive data analytics. You can make beautiful data-driven,
interactive and collaborative documents with SQL, Scala and more.

4. When do you need Zeppelin?
Engineers Data Scientists Business user
Visualizations
Access control
Report
When multiple tools and different peoples are involved in your data pipeline
JDBC

5. Notebook
Zeppelin allows use multiple interpreter
(language backend) at the same time
● Real-time collaboration
● Authentication
● Notebook ACL
● Interpreter ACL
● Fine grained interpreter session -
notebook/user mapping
● Built-in scheduler
● Pluggable notebook storage
● Pluggable interpreter
Zeppelin supports multi-user environment

6. Built-in Visualization
6 Basic visualizations are built-in, (in addition to matplotlib, ggplot integration)
(Table, Bar chart, Pie chart, Area chart, Scatter chart, Line chart)

8. Why isn’t it easy to add new visualizations?
- Dependent on Zeppelin release cycle
- Restricted License (e.g. commercial chart)
Problems: Built-in Visualizations
“What if I want to display things differently?”

9. Let’s add pluggable visualizations
- external add-ons
- can update frequently
- highly customizable
- shared via online registry
Solution?
Problems: Built-in Visualizations
Why isn’t it easy to add new visualizations?
- Restricted License (e.g. highchart)
- Dependent on Zeppelin release cycle

10. Apache Zeppelin: Helium
VISUALIZATION
DEMO

11. Helium Visualization Examples

12. “What about extending Interpreters?”
“Can we leverage Helium framework for interpreters?”

13. Backgrounds: Interpreter
Execute paragraph (code) and return output
- separated JVM process
- %spark, %jdbc, %python, ...

14. Apache Zeppelin: Helium
SPELL

15. It is not easy to add a new interpreter
- interpreters written in Java
- sometimes need to handle HTML dynamically
Can’t be combined with other interpreters
- e.g. Spark + Markdown
- Interpreter != Display System
Problems: Backend Interpreter
“Can we write interpreters easily?”

16. Backgrounds: Display System
customize interpreted outputs in frontend
- can be combined with interpreters
- %html, %table, %angular, ...

17. Problems: Backend Interpreter
“Frontend interpreter can be a display system”

18. Easy to create and handle HTML
- written in JS
- can utilize many existing JS libraries
(flowchart, sigmajs, vega, papaparse, ...)
Can be a display system like %html, %table
- e.g. Spark Interpreter + Markdown Display
- allows to customize output %myGraph
SPELL: Frontend Interpreter

22. How can we share
VISUALIZATION or
SPELL
packages?

23. ONLINE REGISTRIES

24. ONLINE REGISTRIES

25. ONLINE REGISTRIES

26. Online Registry for Helium packages?

27. THEN WE SHOULD CONSIDER
1. Who/ How can we build up the infra and operate the service?
- Need to set up the authentication system
- Need user/ package DB
- Versioning/ building / packaging
- …
2. External library Licenses

28. Too complicated..
Is there any other SIMPLE way to solve this?

29. A SOLUTION ALREADY EXISTED

30. A SOLUTION ALREADY EXISTED
Helium VISUALIZATION & SPELL packages are
package

31. A SOLUTION ALREADY EXISTED
The package information can be saved in registry!
Helium VISUALIZATION & SPELL packages are
package

32. Then, is there any way to fetch
ONLY Helium package information
from registry?

33. Create
a Helium package
HOW?

34. HOW?
Publish it to
Registry
http://registry.npmjs.org/
Create
a Helium package

35. HOW?
Publish it to
Registry
Filter Helium pkg
& fetch only
necessary metadata
Create
a Helium package

36. HOW?
Publish it to
Registry
Does the package has zeppelin-vis or
zeppelin-spell as its dependency?
Filter Helium pkg
& fetch only
necessary metadata
Create
a Helium package

37. HOW?
Publish it to
Registry
If so, take only necessary metadata:
- name
- description
- version
- license
- ...
Filter Helium pkg
& fetch only
necessary metadata
Create
a Helium package

38. HOW?
Publish it to
Registry
Integrate
whole data and create
helium.json
Filter Helium pkg
& fetch only
necessary metadata
Create
a Helium package

39. HOW?
Publish it to
Registry
Integrate
whole data and create
helium.json
Save the file in
Filter Helium pkg
& fetch only
necessary metadata
Create
a Helium package

40. HOW?
Publish it to
Registry
Save the file in
Trigger
Lambda function
every 1 hour using
Integrate
whole data and create
helium.json
Filter Helium pkg
& fetch only
necessary metadata
Create
a Helium package

41. HOW?
Publish it to
Registry
Read
helium.json
Integrate
whole data and create
helium.json
Trigger
Lambda function
every 1 hour using
Save the file in
Filter Helium pkg

44. JIRA ISSUES
- ZEPPELIN-1973 : List all available Helium packages in Zeppelin website
- ZEPPELIN-2004 : List helium packages in Zeppelin GUI by reading file

45. WHEN CAN I USE THIS?
- Not included in Zeppelin latest version 0.7.X
- Will be available in Zeppelin 0.8.0
- Release plan ?
