git-archive-daemon

git-archive-daemon is a scalable, high-performance HTTP API for serving archives of git repositories.

It utilizes git archive tool for actual archive generation.

Features

• Laziness - Archives are generated on demand, when they're requested.
• Caching - Requests for the same combination of tree, prefix and format are served from a disk cache.
• Work pooling - Archiving is done by workers from a configurable, fixed size pool. This allows for putting predictable, limited load on the machine.
• Request grouping - When the archive is not cached then all requests for it are grouped together, waiting for the single archiving job to complete. This avoids duplicate work and allows git-archive-daemon to handle high volume of requests.
