Unorthodocs: Abandon your DVCS and Return to Sanity – bitquabit

Posted by jpluimers on 2019/11/21

Some interesting thoughts on DVCS: [WayBackUnorthodocs: Abandon your DVCS and Return to Sanity – bitquabit

Besides the very good point it raises about DVCS (Git, Mercurial and most other DVCSes treat the whole state of the repository as the atom) it also indicates quite a few shortcomings:

  • most people hardly ever need the full history to be off-line
  • having the full history means repositories get huge in size, including your off-line clone
  • pseudo-solutions for huge repository sizes – like git-LFS or git-annex – are a no-go because now you loose atomicity
  • huge repositories in file or commit counts make them slow, especially when the trees are deep
  • splitting up repositories isn’t a good idea either because again: you loose atomicity
  • all DVCS are hard, not just git, because they are distributed and full of features
  • the workflow for submitting pull requests is quite a bit longer than submitting a patch, even though merging in a DVCS can be hard too (despite atomicity which does help a lot for DVCS systems)

I see many other advantages of DVCS systems (for instance that you only need to locally have the branches you are interested in, way better tooling for DVCS systems, ditto for sites hosting DVCS), but it always a good thing to know the weak spots of what you are working with.
