Efficient storage, high-speed reading: MySQL’s techniques and strategies for using the Aria engine

Introduction:
As a commonly used relational database management system, MySQL provides a variety of storage engines for users to choose from. . Among them, the Aria engine is a storage engine that supports transactions and concurrent read and write operations, and has efficient storage and high-speed reading characteristics. This article will introduce several techniques and strategies for using the Aria engine to improve MySQL storage and reading performance, and provide corresponding code examples.

1. Basic usage
   The Aria engine has become the default storage engine after MySQL 5.1. Using the Aria engine is very simple. First, specify ENGINE=ARIA when creating the table, for example:

   CREATE TABLE example (
    id INT NOT NULL AUTO_INCREMENT,
    name VARCHAR(100),
    PRIMARY KEY (id)
   ) ENGINE=ARIA;

   Copy after login

   With the above code, we create a table named example and specify the Aria engine as its storage engine.

2. Compress tables to improve storage efficiency
   The Aria engine supports table compression, which can reduce table storage space through compression. You can use ROW_FORMAT=PAGE to specify the row format of the table as PAGE, and set KEY_BLOCK_SIZE when creating the table to control the size of the data block. For example:

   CREATE TABLE compressed_example (
    id INT NOT NULL AUTO_INCREMENT,
    name VARCHAR(100),
    PRIMARY KEY (id)
   ) ENGINE=ARIA ROW_FORMAT=PAGE KEY_BLOCK_SIZE=8;

   Copy after login

   With the above code, we create a table named compressed_example and specify the Aria engine and compression options.

3. Using the concurrent writing feature of the Aria engine
   The Aria engine supports concurrent writing operations, which can be achieved by enabling the concurrent_insert option. You can use the following code to enable concurrent_insert:

   SET GLOBAL aria_concurrent_insert=1;

   Copy after login

   Through the above code, we enable the concurrent_insert option, so that multiple write operations can be performed at the same time, improving write s efficiency.

4. Use the Aria engine's indexing mechanism to optimize reading speed
   The Aria engine uses the B-tree index structure to optimize reading operations. You can use the following code to create an index:

   CREATE INDEX index_name ON example (name);

   Copy after login

   With the above code, we create an index for the name column of the example table. When querying, the Aria engine supports rapid positioning and retrieval of data through indexes, which greatly improves the reading speed.

5. Optimize the cache settings of the Aria engine
   The Aria engine uses caching to improve read and write performance. The size of the cache can be adjusted by setting the aria_pagecache_buffer_size option. For example, you can use the following code to set the cache size to 256M:

   SET GLOBAL aria_pagecache_buffer_size=256M;

   Copy after login

   Through the above code, we set the cache size to 256M, which increases the data caching capability and improves the efficiency of reading and writing. .

Conclusion:
By rationally choosing how to use the Aria engine and optimizing its configuration, the storage and reading performance of MySQL can be improved. This article introduces the basic usage of the Aria engine, techniques and strategies such as table compression, concurrent writing, index optimization, and cache settings, and provides corresponding code examples. I hope readers can flexibly use these techniques in practical applications to improve the performance of MySQL databases.
