Abstract
Techniques for processing metadata (MD) may include: determining, in accordance with one or more criteria, a plurality of MD blocks that are similar and expected to have matching corresponding portions of MD in at least some of the plurality of MD blocks; forming a MD superblock including the plurality of MD blocks; filtering the MD superblock and generating a filtered MD superblock, wherein said filtering includes rearranging content of the MD superblock so that a first plurality of MD portions that are similar are grouped together in the filtered MD superblock, wherein at least some of the first plurality of MD portions that are similar are expected to match; and compressing the filtered MD superblock and generating a compressed filtered MD superblock. Filtering may include performing a bitshuffle algorithm that includes performing a bitwise transpose of a matrix of the MD blocks in the MD superblock.
