Data Modeling Patterns with Cassandra

Did you ever want to model data for lightning fast write and queries with Cassandra? Do you always wonder how to work with Cassandra specific features like TTL and timestamp?

At This Meetup You Will Learn:

• Efficient data modeling that will help you leverage Cassandra to its full potential

• Example super modeling techniques

• Cassandra do's and don'ts + tips and tricks

Come and meet us, we are happy to share all this with you!

Abstract

• Modeling with compound primary key

• Design constraints: ordering of components, unicity by tuple

• grouping by component: how to

• sparse column name type for future insertion

• partitioning very wide rows

• Modeling with Counters

• common operations on counters, effective usage

• rating system with multi-counters

• counting votes with aggregation

• storing real time metrics

• Time to live, the killer-feature

• volatile data

• auto cleaning process

• natural countdown

• rate limiting, yet another great usage of TTL
