while reading the release notes of git 2.11 I noticed a cool new feature has been merged:
If the filter command (a string value) is defined via
filter.<driver>.processthen Git can process all blobs with a single filter invocation for the entire life of a single Git command.
see the git documentation.
This has been developed in the context of git-lfs (see PR 1382).
If I understand correctly how it works this could speed up v6 repos. Looking at the history/website of git-annex there doesn't seem to be yet any work on this so I though it was worth calling the attention on the feature.
Thanks a lot for all the work on git-annex, it's a really amazing project! The more I study it the more cool features I discover
