---------------------------------------------
Summary: Add CQL Data Modeler to tree
Key: CASSANDRA-12054
URL: https://issues.apache.org/jira/browse/CASSANDRA-12054
Project: Cassandra
Issue Type: New Feature
Reporter: Sebastian Estevez
cassandra-stess, like many powerful tools, is not easy to use. It requires some
statistical understanding and syntactic skill, in order to get up and running
with even a simple data model, user profile driven test (for details see the
cassandra-stress docs). Furthermore, designing a good cassandra data model
requires basic understanding of how CQL works and how c* data is laid out on
disk as a result of partitioning and clustering.
The CQL DataModeler aims to simplify this task, getting users up and running
with user profile powered cassandra-stress tests in minutes.
Given the feedback the community has voiced about the usability of
cassandra-stress at NGCC, it was suggested that I contribute the data modeler
to the open source project so it can be maintained in tree and leveraged by
users.
It is a simple static web application and users should be able to use it by
just opening up index.html with their browser and populating the GUI.

I have developed this as a side project and not as production ready code. I
welcome feedback on how it can be cleaned up and improved.

Future improvements include:
1) Add cluster distributions (currently only size and population are supported)
2) Add functionality so that the histograms display overall distributions
(combining cluster and population distributions for fields)
3) Include batch configuration and insert distribution
4) Include -pop and other command line options that are crucial for describing
workloads
5) Add sparse table capabilities (already in stress but currently undocumented)
6) Add a few example data models to ship with the tool
7) Eventually allow users to contribute back profiles to some sort of community
IMO this jira should be contingent on 1, 3, 4, and 6 being completed.
