Abstract
A transaction manager for handling operations on data in a storage system provides a system for executing transactions that uses a versioned tuple cache to achieve fast, abortable transactions using a redo-only log. The transaction manager updates an in-memory key-value store and also attaches a transaction identifier to the tuple as a minor key. Opportunistic locking can be accomplished due to the low cost of aborting transactions.
