Abstract
A system for dynamically varying traffic routing modes in a distributed database system is presented. A database system comprises a load balancer and a database partitioned into a first and second shard. Coupled to the load balancer are a first plurality of database servers and a second plurality of database servers. Each of the first plurality of database servers contains a copy of the first shard of the database. Each of the second plurality of database servers contains a copy of the second shard of the database. Each server in the first plurality of database servers sends queries to a server in the second plurality of database servers using a round-robin system in which servers in the second plurality of database servers take turns processing incoming queries, as a method of distributing load among the multiple servers. Other embodiments also are disclosed.
