Cedrick Lunven | Voxxed Days

Voxxed Days Luxembourg 2019
from Thursday 20 June to Friday 21 June 2019.

Cedrick is Developer Advocate at DataStax where he finds opportunities to share his passions by speaking about developing distributed architectures and implementing reference applications for developers. In 2013, he created FF4j, an open source framework for Feature Toggle which he still actively maintains. He is now contributor in JHipster team.

API for Databases : 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. KillrVideo.com is one of this application, it has been written in 4 languages (Java, C#, NodeJS, Python) 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.

Feature Toggle pour les Microservices


Le Feature Toggle (capacité à activer ou désactiver des fonctionnalités à chaud) peut être très utile dans les architecture distribuées type Microservice. Déclarer un flag une fois, (ex:Monitoring) et tous les services peuvent y accéder. (fonctionnalités transverses).

FF4j est l'implémentation de référence de ce pattern pour la plateforme Java. Dans cette session je vous montre comme il est rapide de le mettre en place dans une application Spring-Boot. Vous avez ainsi directement au feature toggle au travers de la console Web mais également une gestion des propriétés et un monitoring métier.
