> For optimal disk performance, it makes most sense to choose our compression boundaries based on compressed size, not uncompressed. If our compressors could take a target length, and return the number of source bytes they managed to fit into that space, this would permit us to lower the number of disk accesses per read. [~blambov]: you've dived into LZ4. How tricky do you think this might be?
