In Fedora 30, DNF package repository metadata is compressed using the
zchunk format in addition to
gzip formats used previously.
zchunk is a new compression format designed to allow for highly efficient
deltas. When Fedora’s metadata is compressed using
zchunk, DNF will
download only the differences between any earlier copies of the metadata and
the current version. DNF and related tools will see significant reductions
in the size of the metadata they download, especially if they are run on a
