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.
David présentera au cours du déjeuner pourquoi et comment il est passé de la recherche SQL à Elasticsearch en détaillant les apports de ce moteur par rapport à une solution pure Lucene :
- Pourquoi Elasticsearch ?
- L’indexation
- La recherche
- Les agrégations et le principe de navigation par facettes
- La scalabilité horizontale
- La communauté
