Abstract
A node a data grid receives a prepare request identifying data to lock for a first transaction. The prepare request indicates a locking order that is different from a locking order indicated by a prior prepare request of a second transaction using the same data. The node identifies keys that correspond to the data. The keys are co-located on the node. The node ranks the keys to define an order for acquiring locks for the data based on key identifiers that correspond to the keys. The defined order matches a locking order used by the second transaction. The node acquires locks for the data using the defined order.
