camel-paho-kafka-connector sink configuration

When using camel-paho-kafka-connector as sink make sure to use the following Maven dependency to have support for the connector:

<dependency>
  <groupId>org.apache.camel.kafkaconnector</groupId>
  <artifactId>camel-paho-kafka-connector</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel Kafka connector version -->
</dependency>

To use this Sink connector in Kafka connect you’ll need to set the following connector.class

connector.class=org.apache.camel.kafkaconnector.paho.CamelPahoSinkConnector

The camel-paho sink connector supports 61 options, which are listed below.

Name Description Default Priority

camel.sink.path.topic

Name of the topic

null

HIGH

camel.sink.endpoint.automaticReconnect

Sets whether the client will automatically attempt to reconnect to the server if the connection is lost. If set to false, the client will not attempt to automatically reconnect to the server in the event that the connection is lost. If set to true, in the event that the connection is lost, the client will attempt to reconnect to the server. It will initially wait 1 second before it attempts to reconnect, for every failed reconnect attempt, the delay will double until it is at 2 minutes at which point the delay will stay at 2 minutes.

true

MEDIUM

camel.sink.endpoint.brokerUrl

The URL of the MQTT broker.

"tcp://localhost:1883"

MEDIUM

camel.sink.endpoint.cleanSession

Sets whether the client and server should remember state across restarts and reconnects. If set to false both the client and server will maintain state across restarts of the client, the server and the connection. As state is maintained: Message delivery will be reliable meeting the specified QOS even if the client, server or connection are restarted. The server will treat a subscription as durable. If set to true the client and server will not maintain state across restarts of the client, the server or the connection. This means Message delivery to the specified QOS cannot be maintained if the client, server or connection are restarted The server will treat a subscription as non-durable

true

MEDIUM

camel.sink.endpoint.clientId

MQTT client identifier. The identifier must be unique.

null

MEDIUM

camel.sink.endpoint.connectionTimeout

Sets the connection timeout value. This value, measured in seconds, defines the maximum time interval the client will wait for the network connection to the MQTT server to be established. The default timeout is 30 seconds. A value of 0 disables timeout processing meaning the client will wait until the network connection is made successfully or fails.

30

MEDIUM

camel.sink.endpoint.filePersistenceDirectory

Base directory used by file persistence. Will by default use user directory.

null

MEDIUM

camel.sink.endpoint.keepAliveInterval

Sets the keep alive interval. This value, measured in seconds, defines the maximum time interval between messages sent or received. It enables the client to detect if the server is no longer available, without having to wait for the TCP/IP timeout. The client will ensure that at least one message travels across the network within each keep alive period. In the absence of a data-related message during the time period, the client sends a very small ping message, which the server will acknowledge. A value of 0 disables keepalive processing in the client. The default value is 60 seconds

60

MEDIUM

camel.sink.endpoint.maxInflight

Sets the max inflight. please increase this value in a high traffic environment. The default value is 10

10

MEDIUM

camel.sink.endpoint.maxReconnectDelay

Get the maximum time (in millis) to wait between reconnects

128000

MEDIUM

camel.sink.endpoint.mqttVersion

Sets the MQTT version. The default action is to connect with version 3.1.1, and to fall back to 3.1 if that fails. Version 3.1.1 or 3.1 can be selected specifically, with no fall back, by using the MQTT_VERSION_3_1_1 or MQTT_VERSION_3_1 options respectively.

null

MEDIUM

camel.sink.endpoint.persistence

Client persistence to be used - memory or file. One of: [FILE] [MEMORY]

"MEMORY"

MEDIUM

camel.sink.endpoint.qos

Client quality of service level (0-2).

2

MEDIUM

camel.sink.endpoint.retained

Retain option

false

MEDIUM

camel.sink.endpoint.serverURIs

Set a list of one or more serverURIs the client may connect to. Multiple servers can be separated by comma. Each serverURI specifies the address of a server that the client may connect to. Two types of connection are supported tcp:// for a TCP connection and ssl:// for a TCP connection secured by SSL/TLS. For example: tcp://localhost:1883 ssl://localhost:8883 If the port is not specified, it will default to 1883 for tcp:// URIs, and 8883 for ssl:// URIs. If serverURIs is set then it overrides the serverURI parameter passed in on the constructor of the MQTT client. When an attempt to connect is initiated the client will start with the first serverURI in the list and work through the list until a connection is established with a server. If a connection cannot be made to any of the servers then the connect attempt fails. Specifying a list of servers that a client may connect to has several uses: High Availability and reliable message delivery Some MQTT servers support a high availability feature where two or more equal MQTT servers share state. An MQTT client can connect to any of the equal servers and be assured that messages are reliably delivered and durable subscriptions are maintained no matter which server the client connects to. The cleansession flag must be set to false if durable subscriptions and/or reliable message delivery is required. Hunt List A set of servers may be specified that are not equal (as in the high availability option). As no state is shared across the servers reliable message delivery and durable subscriptions are not valid. The cleansession flag must be set to true if the hunt list mode is used

null

MEDIUM

camel.sink.endpoint.willPayload

Sets the Last Will and Testament (LWT) for the connection. In the event that this client unexpectedly loses its connection to the server, the server will publish a message to itself using the supplied details. The topic to publish to The byte payload for the message. The quality of service to publish the message at (0, 1 or 2). Whether or not the message should be retained.

null

MEDIUM

camel.sink.endpoint.willQos

Sets the Last Will and Testament (LWT) for the connection. In the event that this client unexpectedly loses its connection to the server, the server will publish a message to itself using the supplied details.

null

MEDIUM

camel.sink.endpoint.lazyStartProducer

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.
