1.1.2. Centralized vs. Decentralized

  1. Centralized:

    • Single truth

    • Simple revision numbers

    • Timeline is always straight

    • Single point of failure

    • Simpler branches

    • Small number of branches

  2. Decentralized

    • Unable to use incremented int as revision numbers

    • Use hashes

    • All repositories are equal

    • Any repository can have different history

    • More diverged branches

    • Can have many branches

1.2. Design Philosophy

  1. Tracking file permissions

  2. Tracking file renames and moves

  3. Key-Value Storage of Immutable Objects

  4. Working Offline

  5. Efficient Storage
