Abstract: Disclosed is a method, a computer program product, and a computer system for implementing automatic connection load balancing of database connections between instances of a cluster. Load imbalances are detected globally in the cluster, and can be corrected autonomously by the local instances. The local controller/orchestrator detects the imbalance, computes a target for the instance, and makes any necessary adjustments on the instance, where a server marks the connections to redistribute, and then implements draining and/or planned failover to move sessions.
