Lag in databases, particularly in replication setups, refers to the delay between changes on the primary database and their reflection on replicas. For database professionals, minimizing lag is crucial for high availability, real-time analytics, and disaster recovery.
Key Concepts:
Replication lag occurs due to network latency, heavy workloads, slow disk I/O, or inefficient queries. It impacts read consistency, failover times, and system reliability, making proactive monitoring and optimization essential.
Common Challenges & Solutions:
Issues like long-running transactions, inefficient indexing, and hardware limitations contribute to lag. Our blogs provide expert strategies, tuning techniques, and monitoring tools to help mitigate replication delays.
