Effective storage allocation for sequentially-written memory devices

A method comprising:

• receiving, by a processing device, an input/output (I/O) erase request directed at a plurality of memory devices, wherein the I/O erase request comprises a logical block address, wherein the logical block address is associated with a data object, wherein the plurality of memory devices comprises a plurality of zones corresponding to sequential logical addresses, and wherein the plurality of zones are associated with a compound data object associated with a plurality of data objects, wherein the plurality of data objects comprises the data object;
• identifying one or more zones associated with the data object;
• decrementing a data set counter associated each of the one or more zones, wherein the data set counter represents a number of sets of data associated with the zone;
• and
• responsive to determining that the data set counter associated with one of the one or more zones satisfies a criterion, causing an erasure of the one of the one or more zones.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving an input/output (I/O) erase request directed at a plurality of memory devices, wherein the I/O erase request comprises a logical block address, wherein the logical block address is associated with a data object, wherein the plurality of memory devices comprises a plurality of zones corresponding to sequential logical addresses, and wherein the plurality of zones are associated with a compound data object associated with a plurality of data objects, wherein the plurality of data objects comprises the data object;
• identifying one or more zones associated with the data object;
• decrementing a data set counter associated with each of the one or more zones, wherein the data set counter represents a number of sets of data associated with the zone;
• and
• responsive to determining that the data set counter associated with one of the one or more zones satisfies a criterion, causing an erasure of the one of the one or more zones.
