In this post we compare how Cassandra and MariaDB can be configured to operate in clusters and how this affects response time for queries. We found Cassandra to scale well and to be highly configurable. MariaDB can be used with Galera Cluster but it does not provide horizontal scaling. Also NDB can be used to scale MySQL but it was not as configurable as Cassandra.

We've been comparing Cassandra and MariaDB in single node setups, exploring the issues of each in terms of performance and ease of use from a development perspective. In this article we explore the issues at play in such a setup such as the differences in queries, speed of response and the features that seperate these two technologies.

Level-up the state is perhaps the most useful React pattern. Apply it to your dependencies and you can get many benefits, like better tests, flow control and idempotent routes.

I downloaded an analysed the training data for 1,000 athlete who ran the London Marathon in 2016. From this data I've learnt that people put in ~30% less mileage than popular plans suggest, Sunday mornings are a firm favourite for long runs, and that Saturday morning parkruns are very popular!
