SCALABLE GARBAGE COLLECTION

Abstract:

A method of scalable garbage collection includes receiving an indication to perform a garbage collection process on a section of a database of a storage array comprising a plurality of storage devices. The method further includes determining, by a processing device of a storage array controller of the storage array, whether the section corresponds to any check-pointed data set. The method further includes, if the section does not correspond to any check-pointed data set: performing the garbage collection process on the section. The method further includes, if the section does correspond to a check-pointed data set: performing, by the processing device, a scalable garbage collection process on the section.
