Crate git_odb[−][src]

Git stores all of its data as Objects, which are nothing more than data along with a hash over all data. Thus it’s an object store indexed by data with inherent deduplication: the same data will have the same hash, and thus occupy the same space within the database.

There are various flavours of object databases, all of which supporting iteration, reading and possibly writing.

loose::Db
- A database storing one object per file, named by its hash, using zlib compression.
- O(1) reads and writes, bound by IO operations per second
pack::Bundle
- A database storing multiple objects within an indexed pack file, reaching compression ratios of 60 to 1 or more.
- Slow writes and fast reads
compound::Db
- A database using a loose::Db for writes and multiple pack::Bundles for object reading. It can also refer to multiple additional compound::Db instances using git-alternates.
- This is the database closely resembling the object database in a git repository, and probably what most people would want to use.
linked::Db
- A database containing various compound::Dbs as gathered from alternates files.
