tailieunhanh - MySQL Cluster Administrator Guide

MySQL Cluster is a scalable main memory database management system with high performance and high reliability. The system consists of two parts – the MySQL Server and the NDB Cluster storage engine. This manual describes the NDB Cluster storage engine. The MySQL Server is described in the MySQL Reference Manual. The NDB Cluster can be run integrated with the MySQL Server or as a standalone database server. NDB Cluster synchronously replicates the database on several nodes, making the system withstand software and hardware failures without loss of information. Due to the synchronous replication algorithm, take-over of failed nodes is instantaneous. NDB Cluster is highly configurable. | MySQL Cluster Administrator Guide Information about the storage engine used in MySQL Cluster • NDB Cluster Concepts • NDB Cluster Installation • NDB Cluster Configuration Note that this guide is currently being re-written and that the terminology used in this guide may change.
