Storage optimization for write-in-free-space workloads

A computer program product to optimize data storage for write-in-free-space workloads, the computer program product comprising a computer-readable storage medium having computer-usable program code embodied therein, the computer-usable program code configured to perform the following when executed by at least one processor:

• receive a write request to write an updated version of data to a new block address in free space, the new block address mapping to a destination extent;
• determine an old block address storing a previous version of the data, the old block address mapping to a source extent;
• determine whether the source extent is the same as the destination extent;
• if the source extent is not the same as the destination extent, transfer temperature statistics associated with the old block address from the source extent to the destination extent;
• and
• write the updated version of the data to the new block address.

A system to optimize data storage for write-in-free-space workloads, the system comprising:

• at least one processor;
• at least one memory device operably coupled to the at least one processor and storing instructions for execution on the at least one processor, the instructions causing the at least one processor to:
• receive a write request to write an updated version of data to a new block address in free space, the new block address mapping to a destination extent;
• determine an old block address storing a previous version of the data, the old block address mapping to a source extent;
• determine whether the source extent is the same as the destination extent;
• if the source extent is not the same as the destination extent, transfer temperature statistics associated with the old block address from the source extent to the destination extent;
• and
• write the updated version of the data to the new block address.
