Is there any way to completely eliminate replication lag in a distributed database?

Traditional asynchronous replication often suffers from slave lag because the secondary nodes are always trying to catch up to the primary. However, if you use a MariaDB Galera Cluster, it uses synchronous multi-master replication. This means every node in the cluster acts as a master, and transactions are confirmed across all nodes before they are committed.

Because of this certification-based approach, you essentially get zero replication lag. Every node stays in a consistent state in real-time. If the manual setup of such a cluster feels daunting, a managed cloud platform like AccuWeb.Cloud provides built-in mechanisms to ensure this consistency is maintained without needing deep DBA expertise.
