# Tari Storage
This crate is part of the [Tari Cryptocurrency](https://tari.com) project.
An abstraction layer for persistent key-value storage. The Tari domain layer classes should only make use of these
traits and objects and let the underlying implementations handle the details.
## DataStore
Provides a general CRUD behaviour of Key-Value Store implementations. `Datastore` is agnostic of the underlying
implementation.
## LMDB
Currently, Tari supports LMDB for local disk persistence.
Use `LMDBBuilder` to open/create a new database.
```rust,ignore
# use tari_storage::lmdb::LMDBBuilder;
let mut store = LMDBBuilder::new()
.set_path("/tmp/")
.set_mapsize(500)
.add_database("db1")
.add_database("db2")
.build()
.unwrap();
```
