Description:

Scalar is a tool that helps Git scale to some of the largest Git repositories.
It achieves this by enabling some advanced Git features, such as:
* Partial clone: reduces time to get a working repository by not downloading
all Git objects right away.
* Background prefetch: downloads Git object data from all remotes every hour,
reducing the amount of time for foreground git fetch calls.
* Sparse-checkout: limits the size of your working directory.
* File system monitor: tracks the recently modified files and eliminates the
need for Git to scan the entire worktree.
* Commit-graph: accelerates commit walks and reachability calculations,
speeding up commands like git log.
* Multi-pack-index: enables fast object lookups across many pack-files.
* Incremental repack: Repacks the packed Git data into fewer pack-file
without disrupting concurrent commands by using the multi-pack-index.
