Abstract
In response to a request from a client to store a data block in a storage system, the data block is segmented into a plurality of subblocks. Each of the plurality of subblocks is individually compressed into a compressed subblock. The compressed subblocks are packed into a compressed data block. The compressed data block having the individually compressed subblocks therein is stored in a persistent storage device. Metadata of the compressed data block is stored in an index entry in an index of the storage system, including storing subblock locators indicating locations of the compressed subblocks. Each of the subblocks can be individually accessed based on a corresponding subblock locator without having to access remaining subblocks.
