Git stores all of its data as Objects, which are data along with a hash over all data. Thus it's an object store indexed by the signature of data itself with inherent deduplication: the same data will have the same hash, and thus occupy the same space within the store.
There is only one all-round object store, also known as the [Store], as it supports everything most of what git has to offer.
- loose object reading and writing
- access to packed objects
- multiple loose objects and pack locations as gathered from
alternatesfiles.
