WORKLOAD INSPIRED INPUT SELECTION OF DATABASES FOR RESHARDING

Abstract: methods, systems, and devices for data management are described. a database server may identify workload metrics for a set of database instances and generate a weighted sum of the workload metrics for each database distance. the database server may select, for a resharding operation, a first set of database instances and a second set of database instances, and the selection may be based on a relationship between a first sum of one or more respective weighted sums for the database instances in the first set and a second sum of one or more respective weighted sums for the database instances in the second set. the database server may execute the resharding operation that results in the first set continuing to be supported by the first database server and the second set being supported by the second database server.
