do MORE with stateLESS Elasticsearch

How would you create Elasticsearch if you were starting this project in 2025?

  • Decouple compute from storage
  • Externalize persistence and replication management to a blob store like S3, Google Cloud Storage or Azure Blob Storage
  • Dynamically add or remove instances
  • Have the right default values
  • And a super clear and smooth path for developers

This is exactly what we did with Elastic Serverless.

In this session, you will discover how we redesigned Elasticsearch to do more with a Stateless architecture that can run queries on cold storage.

Comment feriez-vous pour créer Elasticsearch si vous commenciez ce projet en 2025 ?

  • Découpler le calcul (compute) du stockage (storage)
  • Externaliser la gestion de la persistence et la réplication à un blob store comme S3, Google Cloud Storage ou encore Azure Blob Storage
  • Dynamiquement ajouter ou supprimer des instances
  • Avoir les bonnes valeurs par défaut
  • Et un chemin hyper clair et fluide pour les développeurs

C’est exactement ce que nous avons fait avec Elastic Serverless.

Lors de cette session, vous allez découvrir comment nous avons re-conçu Elasticsearch pour lui permettre d’en faire davantage avec une architecture Stateless qui peut exécuter des requêtes sur un espace de stockage froid (cold storage).

Details

I discovered Elasticsearch project in 2011. After contributed to the project and created open source plugins for it, David joined elastic the company in 2013 where he is Developer and Evangelist. He also created and still actively managing the French spoken language User Group. At elastic, he mainly worked on Elasticsearch source code, specifically on open-source plugins. In his free time, he likes talking about elasticsearch in conferences or in companies (Brown Bag Lunches AKA BBLs ). He is also author of FSCrawler project which helps to index your pdf, open office, whatever documents in elasticsearch using Apache Tika behind the scene.
