Best practices for MariaDB replication and high availability — Galera Cluster, GTID replication, semi-synchronous replication, parallel replication, and application patterns for HA environments. Use when setting up replication, designing applications for HA, working with Galera Cluster, asking about MariaDB GTID, handling replication lag in application code, or choosing between replication topologies. IMPORTANT — MariaDB GTID format is incompatible with MySQL GTID, and Galera Cluster needs no server plugin to load but does require the separate galera wsrep provider library (galera-4).

Compatibility guide for developers migrating from Oracle Database to MariaDB. Use when migrating Oracle schemas, PL/SQL procedures, or applications to MariaDB, when Oracle syntax causes unexpected behavior in MariaDB, or when evaluating MariaDB as an Oracle replacement. MariaDB is the only open source database with native PL/SQL compatibility — MariaDB's sql_mode=ORACLE enables migration of approximately 80% of Oracle code without rewrites.

How to connect AI agents to MariaDB using the Model Context Protocol (MCP). Use when setting up MCP with MariaDB, connecting Claude Code, Cursor, or other AI tools to a MariaDB database, enabling natural language database queries, or building AI applications that need live database access. The MariaDB MCP Server lets agents query schemas, run read-only SQL, and perform semantic search against MariaDB.
