The article traces MySQL’s origins from Monty Widenius’s early Unireg project through its rapid growth, acquisition by Sun and Oracle, and the emergence of MariaDB, highlighting how an open‑source, user‑focused ecosystem and the LAMP stack propelled MySQL to become the world’s most popular database.
Running ANALYZE TABLE on MySQL, Percona Server, or MariaDB can block queries in older versions, but from MySQL 8.0.24, Percona Server 5.6.38+, 5.7.20+, and MariaDB 10.5.4+, the operation is safe and no longer causes disruptive locks.
This article presents five expansion strategies—shutdown, write‑stop, log‑based, dual‑write, and smooth 2N—detailing step‑by‑step procedures for MariaDB installation, master‑master replication, dynamic data‑source configuration, and Keepalived high‑availability setup, enabling seamless horizontal scaling and minimal service disruption for large‑scale databases.
The article explains that MySQL’s legacy “utf8” charset only supports three‑byte characters, causing errors with genuine four‑byte UTF‑8 symbols, and advises all MySQL/MariaDB users to migrate to the proper “utf8mb4” charset using available conversion guides.
This article examines the current state and historical background of MySQL and MariaDB service lifecycles and version‑management strategies, comparing their community‑edition release models, long‑term‑support policies, innovation releases, and upgrade paths.
This article analyzes why the MariaDB audit plugin crashes on MySQL 5.7, presents compatibility tables before and after source modification, details the verification steps, and provides a step‑by‑step solution including source code changes and recompilation to make the plugin work reliably.
This article introduces Sequel Pro, a macOS GUI client for MySQL and MariaDB, explains how to configure standard connections with required fields, describes the main interface features such as database selection, table structure and content viewing, and highlights additional tools like Query and Table Info.
This technical guide explains how to scale a sharded database horizontally by introducing five expansion schemes—including shutdown, write‑stop, log‑based, dual‑write, and smooth 2N approaches—covers MariaDB installation, master‑master replication setup, dynamic data‑source configuration with ShardingJDBC, and detailed Keepalived high‑availability configuration for seamless service continuity.
This article explains how to expand a sharded database from three to four nodes, compares five migration schemes—including stop‑service, stop‑write, log‑based, dual‑write, and smooth 2N approaches—and provides step‑by‑step instructions for MariaDB installation, master‑slave configuration, Keepalived high‑availability setup, and dynamic data‑source integration using ShardingJDBC.
This article presents a detailed analysis and step‑by‑step implementation of horizontal database scaling, including sharding strategies, shutdown and stop‑write plans, log‑based migration, dual‑write approaches, and a smooth 2N expansion method, while also covering MariaDB master‑master configuration, dynamic data source addition, and Keepalived high‑availability setup.
This guide explains how to deploy and configure MariaDB MaxScale as a database proxy to achieve MySQL read/write splitting, covering topology design, user creation, installation steps, configuration files, service setup, and verification of routing behavior.
MariaDB 10.10.1 RC and 10.9.2 GA have been released, delivering a short‑term support series with numerous bug fixes and improvements for InnoDB, replication, Galera clustering, the optimizer and other core components, enhancing stability and performance for database users.
This article explains three practical methods for adding audit capabilities to MySQL 5.7—using the init_connect parameter to log user connections, installing the MariaDB server_audit plugin for detailed event logging, and deploying the McAfee audit plugin—while providing step‑by‑step commands, configuration examples, code snippets, and a comparison of advantages and drawbacks.
