Pippin is a database inspired by distributed version control systems (notably git). Unlike git it is designed to store thousands to millions (or more) small objects in only a few dozen files. Unlike regular databases, it is designed with distributed synchronisation in mind and convenient access to objects of a single user-defined type. Pippin does not (currently) have a true index for searching its database, but does have partitioning to reduce searches to a smaller subset.
For more, see the documentation in src/lib.rs or take a look at the examples.
Pippin is 'alpha' status. Some of the core features work fine:
- persistance of data within a single 'partition' via snapshots and change logs
- checksumming
Some are only partially there:
- real partitioning support
- merging of conflicting changes
The doc directory contains some file-format documentation and various notes planning Pippin's development.
Tickets were originally stored in files. Several "tags" are still in use; where applicable these are mentioned in tickets and can be used to find relevant bits of code. All of these can be found with grep:
egrep -IR "#00[0-9]{2}" doc/ src/
Pippin uses Cargo. A few example commands:
cargo test
cargo build --release
cargo run --example pippincmd -- -h
cargo help run
cargo doc && open target/doc/pippin/index.html
Generated binaries can be found in the target directory.
