Supporting transactions in distributed environments using a local copy of remote transaction data and optimistic locking

摘要

A first process executing in a computer system in a data grid receives a request to perform at least one transaction operation of a transaction based on remote transaction data of at least one other process in the data grid. The at least one other process is capable to perform a prepare operation for a transaction. The first process identifies a local copy of the remote transaction data in a local data structure and performs the at least one transaction operation using the local copy of the remote transaction data without acquiring a lock on the remote transaction data.
