 Dateilager is a content-addressed, networked filesystem for keeping large, similar directories among a wide variety of hosts. It has a few key properties:
 
- - file contents and versions are stored in by a central server, with readers and writers as clients
- - files and trees of files are stored only once in a content-addressed store by the server for efficiency, but are still served securely to only clients with access
- - readers and writers keep a copy of the filesystem synced locally for very fast local access (and trade off consistency or atomicity)
- - incremental updates by readers are O(changes) and optimized to be very fast
- - one Dateilager server supports storing many different independent filesystems with secured access to each (multi-tenancy)

 Dateilager is used in production to power https://gadget.dev to sync the filesystems for all the apps on the Gadget platform. Dateilager shines at syncing the (often very large) `node_modules` folder shared between the many node.js applications, as well as the comparatively small `.js` files comprising the actual business logic of one particular app.
