Abstract
A partial-blocking consistency point system identifies transaction updates with a consistency point ID associated with a consistency point sequence number, records consistency point data that identify a location of the partial-blocking consistency point, flushes to a non-volatile storage the transaction updates identified with the consistency point sequence number without blocking transaction activity, and hardens to the non-volatile storage the recorded partial-blocking consistency point so that data associated with the recorded partial-blocking consistency point can be recovered. The consistency point sequence number is incremented each time the partial-blocking consistency point is recorded to uniquely identify the partial-blocking consistency point and transaction updates associated with the partial-blocking consistency point. The transaction updates identified with the consistency point sequence number are processed to improve efficiency of the flushing of the transaction updates.
