# Replication

- [Replication Overview](/docs/server/ha-and-performance/standard-replication/replication-overview.md): Explore the core concepts of MariaDB standard replication. Learn about the primary-replica architecture, data redundancy strategies, and how to scale read operations effectively.
- [Choosing a Replication Strategy](/docs/server/ha-and-performance/standard-replication/choosing-a-replication-strategy.md)
- [Replication Statements](/docs/server/ha-and-performance/standard-replication/replication-statements.md): Access the complete reference of SQL statements used to manage replication. This guide covers commands for controlling primaries, configuring replicas, and monitoring status.
- [Setting Up Replication](/docs/server/ha-and-performance/standard-replication/setting-up-replication.md): Complete guide to MariaDB replication setup. Complete walkthrough for primary-replica topology with binary logging and GTID configuration.
- [Global Transaction ID](/docs/server/ha-and-performance/standard-replication/gtid.md): Complete GTID replication reference: CHANGE MASTER master\_use\_gtid=current\_pos|slave\_pos, gtid\_slave\_pos table (InnoDB), START REPLICA UNTIL master\_gtid\_pos.
- [Read-Only Replicas](/docs/server/ha-and-performance/standard-replication/read-only-replicas.md): Learn how to configure replicas as read-only instances. This ensures data integrity by preventing accidental writes on the replica while allowing it to process replication events.
- [Multi-Source Replication](/docs/server/ha-and-performance/standard-replication/multi-source-replication.md): Discover how to replicate data from multiple primaries to a single replica. This guide covers the configuration for aggregating data from different sources into one MariaDB instance.
- [Multi-Master Ring Replication](/docs/server/ha-and-performance/standard-replication/multi-master-ring-replication.md): Explore the ring topology where each server acts as both primary and replica. Learn the configuration steps and caveats for setting up a circular replication environment.
- [Delayed Replication](/docs/server/ha-and-performance/standard-replication/delayed-replication.md): Learn to configure a time lag for your replica. Delayed replication helps recover from human errors on the primary, such as accidental drop commands, by preserving older states.
- [Parallel Replication](/docs/server/ha-and-performance/standard-replication/parallel-replication.md): Boost MariaDB Server replication performance with parallel replication. This section explains how to configure replicas to apply events concurrently, reducing lag and improving throughput.
- [Semisynchronous Replication](/docs/server/ha-and-performance/standard-replication/semisynchronous-replication.md): Enhance data consistency with semisynchronous replication. Ensure that the primary waits for at least one replica to acknowledge receipt of a transaction before committing.
- [Row-based Replication With No Primary Key](/docs/server/ha-and-performance/standard-replication/row-based-replication-with-no-primary-key.md): Understand the performance implications and best practices for replicating tables without primary keys when using row-based logging, including how to avoid full table scans.
- [Unsafe Statements for Statement-Based Replication](/docs/server/ha-and-performance/standard-replication/unsafe-statements-for-statement-based-replication.md): Identify SQL statements that are non-deterministic and unsafe for statement-based replication. Learn why these queries cause divergence and how to switch to row-based logging.
- [Replication Filters](/docs/server/ha-and-performance/standard-replication/replication-filters.md): Learn how to filter specific databases or tables from being replicated. This guide covers configuration options to replicate only the data you need on specific replicas.
- [Replication Threads](/docs/server/ha-and-performance/standard-replication/replication-threads.md): Gain insight into the background threads that drive replication. Understand the roles of the I/O thread, SQL thread, and binlog dump thread in moving data between servers.
- [Replication and Foreign Keys](/docs/server/ha-and-performance/standard-replication/replication-and-foreign-keys.md): Understand how foreign key constraints interact with replication. Learn best practices for managing cascading deletes and updates across primary and replica servers.
- [Replication and Binary Log System Variables](/docs/server/ha-and-performance/standard-replication/replication-and-binary-log-system-variables.md): Complete Replication and Binary Log System Variables reference for MariaDB. Complete guide for configuration values, scope settings, and performance impact.
- [Replication and Binary Log Status Variables](/docs/server/ha-and-performance/standard-replication/replication-and-binary-log-status-variables.md): View the status variables used to monitor replication health. Learn how to interpret metrics regarding log positions, connection status, and event counts.
- [Binlog Event Checksum Interoperability](/docs/server/ha-and-performance/standard-replication/binlog-event-checksum-interoperability.md): Learn about checksum compatibility between different MariaDB versions. Ensure older replicas can correctly verify binary log events generated by newer primaries.
- [Binlog Event Checksums](/docs/server/ha-and-performance/standard-replication/binlog-event-checksums.md): Configure checksums to detect data corruption in binary logs. Learn how to enable verification to ensure the integrity of replication events during transmission and storage.
- [Changing a Replica to Become the Primary](/docs/server/ha-and-performance/standard-replication/changing-a-replica-to-become-the-primary.md): Follow the procedure to promote a replica to a primary role. This guide details the steps for planned failovers or topology reorganization with minimal downtime.
- [Replication When the Primary and Replica Have Different Table Definitions](/docs/server/ha-and-performance/standard-replication/replication-when-the-primary-and-replica-have-different-table-definitions.md): Understand the rules and limitations when replicating between tables with differing structures. Learn how attribute promotion and column handling work in row-based replication.
- [START TRANSACTION ... WITH CONSISTENT SNAPSHOT](/docs/server/ha-and-performance/standard-replication/enhancements-for-start-transaction-with-consistent-snapshot.md): Learn how to start a consistent transaction for backups or replication setup. This command ensures a consistent view of the database without locking tables unnecessarily.
- [Restricting Speed of Reading Binlog from Primary by a Replica](/docs/server/ha-and-performance/standard-replication/restricting-speed-of-reading-binlog-from-primary-by-a-replica.md): Configure throughput limits for replication traffic. Learn to throttle the binlog download speed to prevent replication from consuming all available network bandwidth.
- [Running Triggers on the Replica for Row-based Events](/docs/server/ha-and-performance/standard-replication/running-triggers-on-the-replica-for-row-based-events.md): Understand how triggers behave under row-based replication. Learn when and why triggers are not executed on the replica and how to manage complex logic in this mode.
- [Obsolete Replication Information](/docs/server/ha-and-performance/standard-replication/obsolete-replication-information.md): Access documentation for deprecated or removed replication features. Review this historical context when upgrading legacy systems or migrating to newer MariaDB versions.
