a tokio-enabled data store for triple data
This library implements a way to store triple data - data that consists of a subject, predicate and an object, where object can either be some value, or a node (a string that can appear both in subject and object position).
An example of triple data is:
cow says value(moo). duck says value(quack). cow likes node(duck). duck hates node(cow).In
cow says value(moo),
cowis the subject,
saysis the predicate, and
value(moo)is the object.
cow likes node(duck),
cowis the subject,
likesis the predicate, and
node(duck)is the object.
terminusdb-store allows you to store a lot of such facts, and search through them efficiently.
This library is intended as a common base for anyone who wishes to build a database containing triple data. It makes very few assumptions on what valid data is, only focusing on the actual storage aspect.
This library is tokio-enabled. Any i/o and locking happens through futures, and as a result, many of the functions in this library return futures. These futures are intended to run on a tokio runtime, and many of them will fail outside of one. If you do not wish to use tokio, there's a small sync wrapper in
store::syncwhich embeds its own tokio runtime, exposing a purely synchronous API.
Add this to your
[dependencies] terminus-store = "0.16"
create a directory where you want the store to be, then open that store with
rust let store = terminus_store::open_directory_store("/path/to/store").await.unwrap();
Or use the sync wrapper:
rust let store = terminus_store::open_sync_directory_store("/path/to/store").unwrap();

We are constantly developing terminusdb-store to make it a high quality succinct graph representation versioned datastorage layer. To help facilitate understanding of our aims for this project we have laid out a Roadmap. If you would like to assist in the development of terminusdb-store, or you think something should be added to the roadmap please contact us.
