Description: MARIADB_REPLICATION refers to the replication features of MariaDB for data redundancy. This functionality allows the data from one database to be copied and kept synchronized across multiple servers, providing greater availability and resilience against failures. Replication in MariaDB can be configured in various ways, including asynchronous, semi-synchronous, and synchronous replication, each with its own advantages and disadvantages. Asynchronous replication, for example, allows transactions to be performed on the primary server without waiting for them to complete on secondary servers, which can improve performance but at the cost of immediate data consistency. On the other hand, semi-synchronous replication offers a balance by ensuring that at least one secondary server receives the transaction before it is confirmed on the primary server. This feature is particularly useful in environments where data availability is critical, as it allows for quick recovery in case of failures. Additionally, MARIADB_REPLICATION facilitates horizontal scalability, allowing applications to distribute the workload across multiple servers, thereby improving the overall system performance. In summary, replication in MariaDB is an essential tool for database management in various enterprise environments, ensuring data integrity and availability.
