Abstract
A proactive switchover process in a distributed database system evaluates available resources for a plurality of database instances based on database performance metrics of the database instances and resource metrics for physical hosts of the database instances. Periodic collection and storing of the metrics dataset provide for estimating a switching time length required for switching a primary database instance candidate with the current primary database instance. Further estimating based on historic values informs the proactive switchover determination.
