Abstract
Techniques for data processing may include: receiving a data chunk of the data set; determining, in accordance with criteria including a compressibility ratio for the data set and a cost ratio of compression computation cost and entropy computation cost, whether to activate or deactivate entropy computation for the data set, wherein the compressibility ratio is ratio of a number of compressible data chunks of the data set and a number of uncompressible data chunks of the data set; and responsive to determining to activate entropy computation for the data set, performing first processing comprising: determining an entropy value for the data chunk; and determining, in accordance with the entropy value for the data chunk, whether to compress the data chunk.
