Database replication based on data access scores

Abstract:

Techniques described herein relate to data replication processes, data migration, and other data transfers between physical storage devices. Embodiments include calculating data access metrics for particular database objects, and initiating data replication processes and/or other data transfers for determined subset of the database objects based on the access metrics for the subsets of database objects. Data access metrics may be determined for particular database objects stored within a database, cloud-based storage, or other physical storage device, or across multiple storage devices. Based on the data access scores of various database objects, a replication engine or other data transfer system may determine particular subsets of database objects to be replicated, and then may initiate a replication process or other data transfer process.
