Starting with version 0.7.2, Garage introduces an optional feature, K2V,
|
|
which is an alternative storage API designed to help efficiently store
|
|
many small values in buckets (in opposition to S3 which is more designed
|
|
to store large blobs).
|
|
|
|
K2V is currently disabled at compile time in all builds, as the
|
|
specification is still subject to changes. To build a Garage version with
|
|
K2V, the Cargo feature flag `k2v` must be activated. Special builds with
|
|
the `k2v` feature flag enabled can be obtained from our download page under
|
|
"Extra builds": such builds can be identified easily as their tag name ends
|
|
with `-k2v` (example: `v0.7.2-k2v`).
|
|
|
|
The specification of the K2V API can be found
|
|
[here](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/main/doc/drafts/k2v-spec.md).
|
|
This document also includes a high-level overview of K2V's design.
|
|
|
|
The K2V API uses AWSv4 signatures for authentification, same as the S3 API.
|
|
The AWS region used for signature calculation is always the same as the one
|
|
defined for the S3 API in the config file.
|
|
|
|
## Enabling and using K2V
|
|
|
|
To enable K2V, download and run a build that has the `k2v` feature flag
|
|
enabled, or produce one yourself. Then, add the following section to your
|
|
configuration file:
|
|
|
|
```toml
|
|
[k2v_api]
|
|
api_bind_addr = "<ip>:<port>"
|
|
```
|
|
|
|
Please select a port number that is not already in use by another API
|
|
endpoint (S3 api, admin API) or by the RPC server.
|
|
|
|
We provide an early-stage K2V client library for Rust which can be imported by adding the following to your `Cargo.toml` file:
|
|
|
|
```toml
|
|
k2v-client = { git = "https://git.deuxfleurs.fr/Deuxfleurs/garage.git" }
|
|
```
|
|
|
|
There is also a simple CLI utility which can be built from source in the
|
|
following way:
|
|
|
|
```sh
|
|
git clone https://git.deuxfleurs.fr/Deuxfleurs/garage.git
|
|
cd garage/src/k2v-client
|
|
cargo build --features cli --bin k2v-cli
|
|
```
|
|
|
|
The CLI utility is self-documented, run `k2v-cli --help` to learn how to use
|
|
it. There is also a short README.md in the `src/k2v-client` folder with some
|
|
instructions.
