MySQL storage engine that supports multi-master replication: Performance optimization and practical experience of NDB Cluster
Introduction:
NDB Cluster is one of the high-availability and scalable storage engines provided by MySQL. It achieves high availability and horizontal scalability of data by implementing a multi-master replication mechanism. This article will introduce the performance optimization method of NDB Cluster and demonstrate practical experience through code examples.
1. Background and advantages of NDB Cluster
NDB Cluster is a special storage engine of MySQL, mainly used to process large-scale data sets (called data slices). It has the following significant advantages:
2. NDB Cluster performance optimization methods
When using the NDB Cluster storage engine, you can take the following methods to improve its performance:
3. Practical experience of NDB Cluster
The following uses code examples to demonstrate how to use NDB Cluster and show some practical experience.
Create NDB Cluster table:
CREATE TABLE `my_table` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(255) DEFAULT NULL, `age` int(11) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=NDBCLUSTER DEFAULT CHARSET=utf8;
Insert data:
INSERT INTO `my_table` (`name`, `age`) VALUES ('John', 25);
Query data:
SELECT * FROM `my_table`;
Update data:
UPDATE `my_table` SET `age` = 30 WHERE `name` = 'John';
Delete data:
DELETE FROM `my_table` WHERE `name` = 'John';
Through the above code example, you can See the simple use of NDB Cluster. In actual applications, further optimization and configuration can be carried out according to specific business needs.
Summary:
NDB Cluster is a powerful and flexible storage engine that can provide high availability and scalability database solutions. When using NDB Cluster, you need to properly design the data structure, avoid excessive indexing, control the number of transactions, and configure reasonable parameters. Through practice and optimization, you can maximize the performance of NDB Cluster.
