I think sysadmins will generally care more about physical space consumption than uncompressed space consumption. > I don't think that we ever report the uncompressed size; > it's only available indirectly by multiplying by the "compressratio" > property. But compressratio is a dataset-wide property -- it seems wrong to assume that it will be the same for each user/group's data inside a given dataset. A fast way to obtain the actual uncompressed data size might be useful, but I also think it should not be a priority if indeed sysadmins care [or ought to care!] more about physical space consumption than uncompressed space consumption.
