摘要：A technique for garbage collection in a storage system includes generatingregrouping metadata for one or more pages of at least two logical erase blocks (LEB).The regrouping metadata indicates an associated stream for each of the pages. Multipleof the LEBs that include valid pages associated with a first stream are selected, based onthe regrouping metadata, for regrouping. The valid pages associated with the firststream from the selected LEBs are regrouped into a new LEB.
