    pub url: String,
    pub qos: Option<QualityOfService>,

}

Fields§

§url: String

The url of the broker to connect to. e.g. tcp://localhost. Must be prefixed with one of either tcp://, mqtt://, ssl://,mqtts://, to denote the protocol for establishing a connection with the broker. mqtts://, ssl:// will use the native certificates if no ca is specified

§qos: Option<QualityOfService>

The quality of service to use when publishing messages. Defaults to at_most_once. Could be at_most_once, at_least_once or exactly_once

§user: Option<String>

Username for the mqtt broker

§password: Option<String>

Password for the mqtt broker

§client_prefix: Option<String>

Prefix for the mqtt client id. The client id will be generated as client_prefixactor_id(executor_id|source_id). Defaults to risingwave

§clean_start: bool

clean_start = true removes all the state from queues & instructs the broker to clean all the client state when client disconnects.

When set false, broker will hold the client state and performs pending operations on the client when reconnection with same client_id happens. Local queue state is also held to retransmit packets after reconnection.

§inflight_messages: Option<usize>

The maximum number of inflight messages. Defaults to 100

§max_packet_size: Option<u32>

The max size of messages received by the MQTT client

§ca: Option<String>

Path to CA certificate file for verifying the broker’s key.

§client_cert: Option<String>

Path to client’s certificate file (PEM). Required for client authentication. Can be a file path under fs:// or a string with the certificate content.

§client_key: Option<String>

Path to client’s private key file (PEM). Required for client authentication. Can be a file path under fs:// or a string with the private key content.
