The Redis open source database has reached what its development team calls a "major milestone", with an "endless" list of new features in the first stable release of its version 2.0.0 iteration.
Described as a "persistent key-value" database with built-in .NET interface written in ANSI-C for Posix systems, the new version includes the MULTI/EXEC family of commands which allow developers to fulfill the need to execute multiple commands as a single atomic block.
This means that if another thread is executing concurrently, it will not interrupt the single block's status -- although each operation will deliver the results of its operations at the same time.
According to the Redis Wiki, "Because all commands inside a MULTI/EXEC block are serialized and executed sequentially, it is not possible that another client request is served in the middle of executing this block. All commands are executed one after the other when EXEC is called, which makes sure either all or no commands are executed, independent of the state of the client connection."
