This bridge connects to a Couchbase cluster using DCP protocol and performs real-time analysis and metadata extraction from stored on the cluster documents. The extracted metadata is then sent to Atlas via its REST API
The bridge uses environment variables for configuration.

| ATLAS_USERNAME | Atlas REST API username | “admin” |
| ATLAS_PASSWORD | Atlas REST API password | “admin” |
| Environment variable | Description | Default Value |
|---|---|---|
| CB_CLUSTER | Couchbase Cluster connection string | “couchbase://localhost” |
| CB_USERNAME | Couchbase Cluster username | “Administrator” |
| CB_PASSWORD | Couchbase Cluster password | “password” |
| CB_ENABLE_TLS | Use TLS | false |
| CB_BUCKET | Couchbase bucket to monitor | “default” |
| CB_COLLECTIONS | Comma-separated list of collections to monitor with each collection listed as . | |
| DCP_PORT | DCP port to use | 11210 |
