Zusammenfassung:Pre-decompressing a compressed form of data that has been pre-fetched into a cache to facilitate subsequent retrieval of a decompressed form of the data from the cache is presented herein. A decompression component retrieves, from a first portion of a cache, a compression chunk comprising compressed data blocks representing a compressed form of a group of data blocks in response to a first cache hit from the first portion of the cache being incurred, decompresses the compression chunk to obtain a decompressed chunk comprising uncompressed data blocks representing an uncompressed form of the group of data blocks, and inserts the uncompressed data blocks into a second portion of the cache. Further, a read component retrieves, from the second portion of the cache, an uncompressed data block of the uncompressed data blocks in response to a second cache hit from the second portion of the cache being incurred.
