# Description

The main responsibility of Colossus is handling media data for users. The data could be images, audio, or video files.
Colossus receives uploads and saves files in the local folder, registers uploads in the blockchain, and later serves files
to Argus nodes (distribution nodes). Colossus instances spread the data using peer-to-peer synchronization.
Data management is blockchain-based, it relies on the concepts of buckets, bags, data objects.
The full description of the blockchain smart contracts could be found [here](https://github.com/Joystream/joystream/issues/2224).

### API

Colossus provides REST API for its clients and other Colossus instances. It's based on the OpenAPI Specification v3. Here is the complete [spec](./src/api-spec/openapi.yaml) (work in progress).

API endpoints:
- files
    - get - get the data file by its ID
    - head - get the data file headers by its ID
    - post - upload a file
- state
    - version - Colossus version and system environment
    - all data objects IDs
    - data objects IDs for bag
    - data statistics - total data folder size and data object number
### CLI

There is a command-line interface to manage Storage Working Group operations like create a bucket or change storage settings. Full description could be found [below](#cli-commands).

There are several groups of command:
- *leader* - manages the Storage Working group in the blockchain. Requires leader privileges.
- *operator* - Storage Provider group - it manages data object uploads and storage provider metadata(endpoint is the most important). Requires active Storage Working group membership.
- *dev* - development support commands. Requires development blockchain setup with Alice account.
- *ungroupped* - server and help commands. `server` starts Colossus and `help` shows the full command list.

### Metadata
The storage provider should provide *metadata* for Colossus instance to be discoverable by other Colossus or
Argus (distributor node) instances. At the very least an endpoint should be registered in the blockchain.
For some complex scenarios, Colossus should provide its geolocation.

Metadata could be registered using [operator:set-metadata](#storage-node-operatorset-metadata) command.
A simple endpoint could be set using the `--endpoint` flag of the command. Complex metadata requires JSON file ([example](./scripts/operatorMetadata.json)).
JSON file format based on the *protobuf* format described [here](../metadata-protobuf/proto/Storage.proto).

### Data
#### Uploading

Colossus accepts files using its API. The data must be uploaded using POST http method with `multipart/form-data`.
Simplified process (file uploading):
   - accepting the data upload in the temp folder
   - data hash & size verification
   - moving the data to the data folder
   - registering the data object as `accepted` in the blockchain

#### Synchronization

Several instances of Colossus should contain the data replica in order to provide some degree of reliability.
When some Colossus instance receives the data upload it marks the related data object as `accepted`.
Other instances that have the same obligations to store the data (they serve storage buckets assigned to the same bag)
will eventually load this data object from the initial receiver (or some other node that already downloaded a new
data object from the initial receiver) using REST API.

#### Distribution

The actual data distribution (serving to end-users) is done via Argus - the distributor node. It gets data from Colossus using the same `get` endpoint on a single data object basis.

### Comments
- Colossus relies on the [Query Node (Hydra)](https://www.joystream.org/hydra/) to get the blockchain data in a structured form.
- Using Colossus as a functioning Storage Provider requires providing [account URI or key file and password](https://wiki.polkadot.network/docs/learn-accounts) as well as active `WorkerId` from the Storage Working group.
