Abstract
Methods and systems for compression of aging data during compaction are disclosed. A method includes: ingesting a plurality of data objects into a dispersed storage network (DSN); determining that a compaction threshold is met for a storage medium in the DSN; and compacting the storage medium, the compaction including, for each of the plurality of data objects: determining a number of times the data object has been compacted; in response to the number of times the data object has been compacted exceeding a predetermined threshold, compressing the data object and rewriting the compressed data object to a new area on a storage medium; and in response to the number of times the data object has been compacted not exceeding the predetermined threshold, rewriting the data object to the new area on the storage medium without compressing the data object.
