Abstract
Systems and methods for providing deferred lock enforcement for transactions are described. The method includes receiving a first request for access to a data resource for a transaction, assigning a first lock to the transaction, and receiving, from a candidate reader, a second request for access to the data resource. The method further includes determining an interpretation of the first lock as i) a first lock type responsive to determining that the transaction is in a read phase or ii) a second lock type responsive to determining that the transaction is in a commit processing phase, and assigning a second lock to the candidate reader responsive to interpreting the first lock as the first lock type, or declining to assign the second lock to the candidate reader responsive to interpreting the first lock as the second lock type.
