Demo time!
Vous utilisez encore des requêtes SQL pour faire des recherches ? Vos utilisateurs vous reprochent de ne pas pouvoir chercher sur toutes les rubriques ? Votre temps de réponse moyen est supérieur à la demi-seconde avec seulement quelques millions de documents ? Il vous faut 3 jours pour produire des statistiques sur vos données ? Vous rêvez d’offrir une recherche “à la google” sur les données de votre SI ?
Ne cherchez plus ! Cette conférence est faite pour vous.
Venez découvrir comment Elasticsearch peut résoudre ces problèmes et bien d’autres lors d’une session basée principalement sur des démonstrations live.
