Abstract
Systems and methods are provided to implement a database connection manager that dynamically routes database query statements to database servers storing replicas of the database. In embodiments, the database connection manager may implement a data access interface that mimics the interface of the database servers, so as to appear to clients as just another database server. In embodiments, various health or performance metrics of the servers are monitored, and the routing may be performed based on the metrics to load balance the servers. In embodiments, the routing may distinguish between read and write statements, so that read statements are routed to servers hosting read-only replicas, and write statements are routed to servers hosting writable replicas. These and other disclosed features improve the functioning of the database, to allow, among other things, the database servers to be dynamically load balanced, and the servers' identities to be hidden from clients.
