More Information
Summary:An apparatus comprises a processing device configured to initiate garbage collection for data pages stored in local storage of a storage node of a storage system. The processing device is also configured to determine, for a given data page stored in the local storage of the storage node, a validity score characterizing a size of changed data in the given data page, and to compare the validity score for the given data page to at least one designated threshold. The processing device is further configured to update a given page object for the given data page in an object store of persistent storage responsive to a first comparison result, and to generate, in the object store of the persistent storage, a page delta object for the given data page responsive to a second comparison result, the page delta object comprising the changed data in the given data page.
