Abstract
Provided are techniques for workload discovery using real-time analysis of input streams. For a meta workload, changes to data objects made by change operations that are in a replication change stream are stored into a recovery log. Using an analytics engine, one of the recovery log and the replication change stream are analyzed to identify associations between the data objects based on usage and access patterns. The associations are used to identify sub-workloads of the meta workload that form consistency groups for replication.

21. A method, comprising:
-
storing, with a processor of a computer, changes to data objects in a source copy made by change operations that are in a replication change stream into a recovery log, wherein the recovery log is an ordered set of discrete, timestamped, recovery log records, and wherein each of the recovery log records comprises the change operation to a data object of the data objects by an application among a plurality of applications; identifying associations between the data objects and the plurality of applications based on usage and access patterns in one of the recovery log and the replication change stream; and using the associations to identify change operations that form consistency groups for replication from the source copy to a target copy, wherein the change operations within each of the consistency groups are executed such that the target copy is a replica of the source copy at a given point in time, and wherein each of the consistency groups comprises a sub-workload; and executing the sub-workloads to perform the replication. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. A computer program product, the computer program product comprising a non-transitory computer readable storage medium having program code embodied therewith, the program code executable by at least one processor to perform:
-
storing changes to data objects in a source copy made by change operations that are in a replication change stream into a recovery log, wherein the recovery log is an ordered set of discrete, timestamped, recovery log records, and wherein each of the recovery log records comprises the change operation to a data object of the data objects by an application among a plurality of applications; identifying associations between the data objects and the plurality of applications based on usage and access patterns in one of the recovery log and the replication change stream; and using the associations to identify change operations that form consistency groups for replication from the source copy to a target copy, wherein the change operations within each of the consistency groups are executed such that the target copy is a replica of the source copy at a given point in time, and wherein each of the consistency groups comprises a sub-workload; and executing the sub-workloads to perform the replication. - View Dependent Claims (29, 30, 31, 32, 33, 34)

35. A computer system, comprising:
-
one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices; and program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to perform operations, wherein the operations comprise; storing changes to data objects in a source copy made by change operations that are in a replication change stream into a recovery log, wherein the recovery log is an ordered set of discrete, timestamped, recovery log records, and wherein each of the recovery log records comprises the change operation to a data object of the data objects by an application among a plurality of applications; identifying associations between the data objects and the plurality of applications based on usage and access patterns in one of the recovery log and the replication change stream; and using the associations to identify change operations that form consistency groups for replication from the source copy to a target copy, wherein the change operations within each of the consistency groups are executed such that the target copy is a replica of the source copy at a given point in time, and wherein each of the consistency groups comprises a sub-workload; and executing the sub-workloads to perform the replication. - View Dependent Claims (36, 37, 38, 39, 40)
