Abstract
(EN)
The present invention relates to autonomous tuning of a data grid of documents in a database. Herein are techniques for storage cells to autonomously maintain local indices and other optimization metadata and algorithms to accelerate selective access into a distributed collection of documents. In an embodiment, each storage cell persists a respective subset of documents. Each storage cell stores, in memory, respective index(s) that map each item to location(s), in one or more documents of the respective subset of documents, where the item occurs. One or more computers execute, based on at least a subset of the indices of the storage cells, a data access request from a database management system. In an embodiment, a cloud of JSON document services provides an easy-to-use, fully autonomous JSON document database that horizontally and elastically scales to deliver fast execution of document transactions and queries without needing tuning by a database administrator.

La présente invention concerne le réglage autonome d'une grille de données de documents dans une base de données. L'invention concerne des techniques pour des cellules de stockage pour maintenir de manière autonome des indices locaux et d'autres métadonnées d'optimisation et des algorithmes pour accélérer un accès sélectif dans une collection distribuée de documents. Dans un mode de réalisation, chaque cellule de stockage maintient un sous-ensemble respectif de documents. Chaque cellule de stockage stocke, en mémoire, un ou des index respectifs qui mappent chaque article sur un ou des emplacements, dans un ou plusieurs documents du sous-ensemble respectif de documents, où l'article se trouve. Un ou plusieurs ordinateurs exécutent, sur la base d'au moins un sous-ensemble des indices des cellules de stockage, une demande d'accès aux données en provenance d'un système de gestion de base de données. Dans un mode de réalisation, un nuage de services de documents ISON fournit une base de données de documents ISON entièrement autonome facile à utiliser qui effectue une mise à échelle horizontale et élastique pour permettre une exécution rapide de transactions et de demandes de document sans avoir besoin de réglage par un administrateur de base de données.
