General MongoDB connection configuration.

Fields

url: String

MongoDB connection string URI. Can contain a comma-separated list of hosts for a replica set. Credentials provided via the separate username and password fields take precedence over any credentials embedded in the URL.

collection: Option<String>

The MongoDB collection name.

username: Option<String>

Optional username. Takes precedence over any credentials embedded in the url. Use embedded URL credentials for simple one-off connections but prefer explicit username/password fields (or environment-sourced secrets) for clarity and secret management in production.

password: Option<String>

Optional password. Takes precedence over any credentials embedded in the url. Use embedded URL credentials for simple one-off connections but prefer explicit username/password fields (or environment-sourced secrets) for clarity and secret management in production.

tls: TlsConfig

TLS configuration.

database: String

The database name.

polling_interval_ms: Option<u64>

(Consumer only) Polling interval in milliseconds for the consumer (when not using Change Streams). Defaults to 100ms.

reply_polling_ms: Option<u64>

(Publisher only) Polling interval in milliseconds for the publisher when waiting for a reply. Defaults to 50ms.

request_reply: bool

(Publisher only) If true, the publisher will wait for a response in a dedicated collection. Defaults to false.

change_stream: bool

(Consumer only) If true, use Change Streams (Subscriber mode). Defaults to false (polling/consumer mode).

request_timeout_ms: Option<u64>

(Publisher only) Timeout for request-reply operations in milliseconds. Defaults to 30000ms.

ttl_seconds: Option<u64>

(Publisher only) TTL in seconds for documents created by the publisher. If set, a TTL index is created.

capped_size_bytes: Option<i64>

(Publisher only) If set, creates a capped collection with this size in bytes.

format: MongoDbFormat

Format for storing messages. Defaults to Normal.

cursor_id: Option<String>

The ID used for the cursor in sequenced mode. If not provided, consumption starts from the current sequence (ephemeral).
