By default, delta will run on cluster mode but users can standup a standalonemode. standalone mode primarily for those who want to run delta in an isolated environment. This mode will create a local database and a local static API key for all requests.
Copy the .env.example file to .env and update the values as needed.
# Node info
NODE_NAME=delta-node
NODE_DESCRIPTION=Experimental Deal Maker
NODE_TYPE=delta-main
# Database configuration
MODE=standalone
DB_DSN=delta.db
DELTA_AUTH=[NODE_API_KEY_HERE]
# Frequencies
MAX_CLEANUP_WORKERS=1500
Here are the fields in the .env file:
NODE_NAME is the name of the node.NODE_DESCRIPTION is the description of the node.NODE_TYPE is the type of the node.MODE can be standalone or cluster. If standalone, the node will run as a single node. If cluster, the node will run as a cluster node.
standalone mode is primarily for those who want to run delta in an isolated environment. This mode will create a local database and a local static API key for all requests. To get a static key, run https://auth.estuary.tech/register-new-token. Copy the generated key and paste it in the DELTA_AUTH field.cluster mode is for those who want to run delta as a cluster. This mode will connect to a remote database. In this mode, you don’t need to specify the DELTA_AUTH field. The node will use the API key provided by Estuary.DB_DSN is the database connection string. If standalone, the node will create a local database. If cluster, the node will connect to a remote database.DELTA_AUTH is the API key used to authenticate requests to the node.MAX_CLEANUP_WORKERS is the maximum number of workers that can be used to clean up the blockstore. This is an optional field. If not specified, the default value is 1500.Put the .env file in the same location as the binary/executable.
With .env file in place, run the following command to start the node in standalone mode.
./delta daemon --mode=standalone
By default, delta will run on cluster mode. This mode will create a local database that can be reconfigured to use a remote HA database and estuary-auth as the authentication and authorizatio component.
When running in cluster mode, users need to register for an API_KEY using the following command.
curl --location --request GET 'https://auth.estuary.tech/register-new-token'
{
"expires": "2123-02-03T21:12:15.632368998Z",
"token": "<API_KEY>"
}
Place the API_KEY in the .env file.
With .env file in place, run the following command to start the node in standalone mode.
./delta daemon --mode=cluster
