Juho Mäkinen shares a Cassandra data and access model for a Facebook-like messenger application:
We have built a facebook style “messenger” into our web site which uses cassandra as storage backend. I’m describing the data schema to server as a simple example how cassandra (and nosql in general) can be used in practice.
Make sure you read the post to better understand how data access patterns are important when deciding your data model.
This blog is called myNoSQL and it is written by me, Alex Popescu, a software architect with a passion for open source and communities.
It records my readings, learnings, and opinions on NoSQL databases, polyglot persistence, and distributed systems -- subjects that I'm passionate about.
The opinions expressed here are my own, and no other party necessarily agrees with them.
If you feel I'm biased, I probably am.
