Hello everyone!

The Cassandra meetup is back after a long break with a big relaunch this March at Monzo's office in Central London!

For this month's edition we're having 3 talks starting at 7:15pm (Pizza will be before the event starts) and we'll live stream it here:

// Speaker 1: Hayato Shimizu, Co-Founder at
// Speaker 2: Matt Heath, Software Engineer at Monzo
// Speaker 2: Cedrick Luven, Developer Advocate at DataStax

// Speaker 1 <> 7:15pm:
Hayato will discuss "Operational management of Apache Cassandra in Enterprises".

Hayato has been using Cassandra since 2010, looking after a large number of Cassandra clusters in both cloud and on-premises environments. He worked as a solutions architect at DataStax, and he is now at a startup providing managed services for Cassandra and DataStax.

// Speaker 2 <> 7:45pm:
Matt Heath from Monzo - "Mistakes were made — Modelling prototypes to critical systems with Cassandra"

Cassandra provides highly scalable resilient data storage for a variety of needs, but its effectiveness is often limited by the way we model our data, design schemas, and determine usage patterns. In this talk Matt will look at some of the design patterns Monzo have adopted and developed, from the prototype stage, to their highly scalable core banking systems.

// Speaker 3 <> 8:15pm:
Cedrick will talk about "Building API for Cassandra Applications : REST, gRPC, GraphQL, which one should you pick?"

Depending on your use cases you may need to access databases with different patterns: CRUD, commands, Streaming, Batches, Asynchronous, Reactive..).

At Datastax, the developer advocates team implements reference applications for developers. We had the chance to implement multiple approaches and can provide feedback. is one of this application, it has been written in 3 languages (Java, C# and Node) and implement API with REST, gRPC and GraphQL. Though live session, browsing real code, you will see implementation details, lessons learnt and get working source code in Github as takeaway.

Special thanks to Monzo who are hosting, live streaming (link will be published soon!) and providing foods and drinks for this event 🙌

Big thanks to long term Cassandra supporter DataStax ( DataStax are one of the largest supporters of the Cassandra project and offer comprehensive support as well as their own distribution of Cassandra, Spark and Solr (DataStax Enterprise).
