ORDERING DATA UPDATES FOR IMPROVING GARBAGE COLLECTION BEING PERFORMED WHILE PERFORMING THE SET OF DATA UPDATES

A computer-implemented method according to one embodiment includes receiving, by a target system from a source system, a description of a set of data updates that are to be written to the target system. For each given portion of data of the target system that is to be rewritten during performance of...

description A computer-implemented method according to one embodiment includes receiving, by a target system from a source system, a description of a set of data updates that are to be written to the target system. For each given portion of data of the target system that is to be rewritten during performance of the set of data updates, forward lookup is performed on the target system for determining a physical storage address of the given portion of data. The method further includes marking each of the determined physical storage addresses of the portions of data of the target system in a copy of a reverse lookup table of the target system. The marked-up reverse lookup table is used for determining an ordering in which the performance of the set of data updates would result in a least amount of garbage collection being performed while performing the set of data updates.
