Feature added by: Michael Schröder (mlschroe) Feature #309561, revision 1 Title: Delta downloads of reposoitory metadata Requested by: Michael Schröder (mlschroe) Description: We already use deltarpms do speed up downloading of rpms when doing an update. Unfortunately, the repository metadata is also quite a chunk of data which considerably slows down update speed. The idea is to use a zsync like algorithm to fetch only the changed parts of the metadata. The implementation will use libcurl's multi interface to work with multiple connections in parallel. Another benefit is that the code can replace the aria2c interface, which does not fit well into the current code (different proxy handling and the like). -- openSUSE Feature: https://features.opensuse.org/309561
