A tool to manage deal replication tracking for onboarding datasets to the Filecoin network via import storage deals. This provides a solution to quickly make deals for massive amounts of data, where the transfer is better handled out-of-band.
The top-level logical grouping of data in DDM is the dataset. Datasets are identified by a name (aka "slug"), along with a replication quota, deal length, and a wallet to make the deals from. Datasets are added independently from the content making them up.
Once a dataset has been created, content may be added to it. A content represents a .CAR file - archive of data that will be shipped to the SP and loaded into their operation. Content is identified by its PieceCID (CommP), has two sizes (raw file size, Padded Piece Size), and also contains a CID of the actual data (Payload CID).
DDM tracks deals to Storage Providers in the network. Add a list of storage providers to DDM before making deals to begin tracking them.
A Replication Profile is what ties a Dataset together with a Provider. It defines the parameters for any deals made to that provider for that dataset. Currently, it allows specifying whether to keep an unsealed copy
and whether to announce to the IPNI
indexer. This allows for flexibility in how deals are made to different providers, such as defining a single SP to host the unsealed copies for retrieval while the others maintain a cold copy for backup.
Once a Dataset, Content, Providers, and a Replication Strategy have been specified, DDM can make replications for the content to the providers. A Replication is a single deal made to a single provider for a single piece of content. Replications are tracked by DDM, and can be queried for status and deal information.
DELTA_AUTH
environment variable to Delta API key. It can also be provided as the CLI flag --delta-auth
localhost:1414
. It must be running or DDM will not start. Override the url by providing specifying the DELTA_API
environment variable, or CLI flag --delta-api
AUTH_URL
environment variable, or CLI flag --auth-url
DDM runs as a daemon, which is a webserver. Start it up with the daemon
command.
./delta-dm daemon
By default, delta-dm daemon
runs on port 1415
. It can be changed with the --port
flag or DELTA_DM_PORT
environment variable.
Once running, you can interact with DDM through the API, CLI, or via the Delta Web frontend

By default, DDM will run using a SQLite database. This is fine for development, but for production use, it is recommended to use a Postgres database. To test this, you can run a Postgres instance in Docker and connect to it with DDM.
docker run --name ddm-postgres -p 5432:5432 -e POSTGRES_PASSWORD=password -d postgres:14.7
psql postgres://postgres:password@localhost:5432/ # to connect to the database
Update the env
file (or --db
flag) to connect to the dev postgres database.
DB_DSN="postgres://postgres:password@localhost:5432/"
