Abstract:
1. A computer-implemented method for natural batching of I/O operations on a replication log, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising: identifying a replication log that records the order of writes within a cluster replication system in order to preserve write order fidelity between a primary site and a secondary site; determining that the replication log is currently unavailable; queuing incoming I/O operations for the replication log in a single batch while the replication log is unavailable; determining that the replication log has become available; ceasing queuing of incoming I/O operations for the replication log based on the determination that the replication log has become available; grouping a plurality of I/O operations in the single batch for processing in parallel by assigning a same generation number to the plurality of I/O operations in response to one of:
