Accelerating Distributed Transactions on Key-Value Stores Through Dynamic Lock Localization

Abstract

Systems and methods for accelerating distributed transactions on key-value stores includes applying one or more policies of dynamic lock-localization, the policies including a lock migration stage that decreases nodes on which locks are present so that a transaction needs fewer number of network round trips to acquire locks, the policies including a lock ordering stage for pipelining during lock acquisition and wherein the order on locks to avoid deadlock is controlled by average contentions for the locks rather than static lexicographical ordering; and dynamically migrating and placing locks for distributed objects in distinct entity-groups in a datastore through the policies of dynamic lock-localization.
