Abstract
Processing and memory resources are optimized in a data storage system by reading a region of compressed data containing desired data is read from primary storage, writing the compressed data to a memory page, selectively decompressing the compressed data to retrieve the desired data, and the writing the decompressed data back to the same page. State information about the start of the compressed data and the end of the decompressed data on the page is maintained to enable decompression to be halted and resumed on demand.
