Title (EN) HANDLING SEMI-STRUCTURED AND UNSTRUCTURED DATA IN A SHARDED DATABASE ENVIRONMENT
(FR) MANIPULATION DE DONNÉES SEMI-STRUCTURÉES ET NON STRUCTURÉES DANS UN ENVIRONNEMENT DE BASE DE DONNÉES PARTITIONNÉE
Abstract:
(EN) Techniques are described herein for leveraging and extending relational data sharding infrastructure to provide comprehensive support for sharding semi-structured and unstructured data, in addition to the relational data, in a single sharded database system. Specifically, techniques are described in which a catalog server pre-gathers all data it needs to answer fetches from a dynamically created temporary lob. In addition, techniques are provided in which a catalog server encodes shard identifiers in lob locators sent to the client. Techniques are provided for pushing down various operators to shard servers.
(FR) L'invention concerne des techniques pour exploiter et étendre une infrastructure de partition de données relationnelles afin de fournir un support complet pour partager des données semi-structurées et non structurées, en plus des données relationnelles, dans un système de base de données partitionné unique. Plus précisément, l'invention concerne des techniques dans lesquelles un serveur de catalogue pré-rassemble toutes les données dont il a besoin afin de répondre aux extraits d'un LOB temporaire créé de manière dynamique. De plus, l'invention concerne des techniques dans lesquelles un serveur de catalogue code des identifiants de partition dans des localisateurs de LOB envoyés au client. L'invention concerne des techniques pour pousser vers le bas divers opérateurs vers des serveurs de partition.
