NoSQL databases scale by adding more commodity servers. With more commodity servers come increased costs and complexities. Some NoSQL systems are better at this than others and need less. Continue reading Operations costs are the Achille’s heel of NoSQL
We live in a notification hell world of smartphones, and every year it is getting worse. Our presumably smart devices are incapable of differentiating what is important and what is not. Continue reading We Live in a Mobile Device Notification Hell
1. Do you know what your queries will look like ? In traditional SQL you design your data model to represent your business objects. Your queries can then evolve over time and can be ad-hoc. You can even create views, materialized or otherwise, to facilitate even more complex analytical queries. Cassandra does not offer the flexibility of traditional SQL. While your data model can … Continue reading Ten Questions to Consider Before Choosing Cassandra
It is 2015 and by now advertising agencies could have figured out the best way to deliver relevant ads to viewers. They have not. Hulu is the prime illustration of this phenomenon.

What this means is that an existing ecosystem of Hadoop applications is immediately binary-compatible with this new service and it doesn’t require any changes to the API. Google is not only marketing this as an alternative to Hadoop, but it is also marketing it as an alternative to … Continue reading We Need a Cloud Version of Cassandra

Apple uses Cassandra for “iMessage, iTunes passwords, a bunch of stuff,” he says. In fact, Apple is touted as having one of the largest production deployments … Continue reading Apple is (or was) the Biggest User of Apache Cassandra
