Replication is a critical feature in distributed systems that ensures data redundancy, high availability, and fault tolerance. It allows multiple copies of data to be maintained across different nodes, enabling seamless operations even in the face of failures.

🧩 Types of Replication

  • Synchronous Replication
    Data is written to all replicas simultaneously. This ensures strong consistency but may introduce latency.

    Synchronous Replication

  • Asynchronous Replication
    Data is written to the primary node first, then propagated to replicas. This reduces latency but may result in temporary inconsistencies.

    Asynchronous Replication

  • Master-Slave Replication
    A single master node handles writes, while slave nodes replicate data for reads.

🛠 Configuration & Best Practices

  1. Enable Replication
    Modify the configuration file: /en/docs/manual/core/replication/config

  2. Monitor Replica Health
    Use tools like replica_status to check synchronization and latency.

  3. Automate Failover
    Implement automated failover mechanisms to ensure minimal downtime.

⚠ Security & Compliance

  • Ensure all replication traffic is encrypted using TLS.
  • Regularly audit replica access logs for unauthorized activities.
  • Comply with data sovereignty laws when replicating across regions.
