In-memory database for high performance, parallel transaction processing

摘要

An in-memory file system supports concurrent clients allowing multiple updates on the same record by more than 1 of the clients, between commits, while maintaining commit integrity over a defined interval of processing. Moreover, a computer system processing transactions includes client computers concurrently transmitting messages. The computer system also includes servers, in communication with the client computers, receiving the messages, and in-memory databases, each in-memory database corresponding, respectively, to at least one of the servers, in which the servers store the messages in records of the respective in-memory databases, and the in-memory databases allow multiple updates on the same record by more than 1 of the client computers, between commits, while maintaining commit integrity over a defined interval of processing.
