camel-nats-kafka-connector sink configuration

Connector Description: Send and receive messages from NATS messaging system.

When using camel-nats-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-nats-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.nats.CamelNatsSinkConnector

The camel-nats sink connector supports 27 options, which are listed below.

Name Description Default Required Priority

camel.sink.path.topic

The name of topic we want to use

null

true

HIGH

camel.sink.endpoint.connectionTimeout

Timeout for connection attempts. (in milliseconds)

2000

false

MEDIUM

camel.sink.endpoint.flushConnection

Define if we want to flush connection when stopping or not

true

false

MEDIUM

camel.sink.endpoint.flushTimeout

Set the flush timeout (in milliseconds)

1000

false

MEDIUM

camel.sink.endpoint.maxPingsOut

maximum number of pings have not received a response allowed by the client

2

false

MEDIUM

camel.sink.endpoint.maxReconnectAttempts

Max reconnection attempts

60

false

MEDIUM

camel.sink.endpoint.noEcho

Turn off echo. If supported by the gnatsd version you are connecting to this flag will prevent the server from echoing messages back to the connection if it has subscriptions on the subject being published to.

false

false

MEDIUM

camel.sink.endpoint.noRandomizeServers

Whether or not randomizing the order of servers for the connection attempts

false

false

MEDIUM

camel.sink.endpoint.pedantic

Whether or not running in pedantic mode (this affects performance)

false

false

MEDIUM

camel.sink.endpoint.pingInterval

Ping interval to be aware if connection is still alive (in milliseconds)

120000

false

MEDIUM

camel.sink.endpoint.reconnect

Whether or not using reconnection feature

true

false

MEDIUM

camel.sink.endpoint.reconnectTimeWait

Waiting time before attempts reconnection (in milliseconds)

2000

false

MEDIUM

camel.sink.endpoint.requestCleanupInterval

Interval to clean up cancelled/timed out requests.

5000

false

MEDIUM

camel.sink.endpoint.servers

URLs to one or more NAT servers. Use comma to separate URLs when specifying multiple servers.

null

false

MEDIUM

camel.sink.endpoint.verbose

Whether or not running in verbose mode

false

false

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.

false

false

MEDIUM

camel.sink.endpoint.replySubject

the subject to which subscribers should send response

null

false

MEDIUM

camel.sink.endpoint.requestTimeout

Request timeout in milliseconds

20000L

false

MEDIUM

camel.sink.endpoint.connection

Reference an already instantiated connection to Nats server

null

false

MEDIUM

camel.sink.endpoint.traceConnection

Whether or not connection trace messages should be printed to standard out for fine grained debugging of connection issues.

false

false

MEDIUM

camel.sink.endpoint.secure

Set secure option indicating TLS is required

false

false

MEDIUM

camel.sink.endpoint.sslContextParameters

To configure security using SSLContextParameters

null

false

MEDIUM

camel.component.nats.servers

URLs to one or more NAT servers. Use comma to separate URLs when specifying multiple servers.

null

false

MEDIUM

camel.component.nats.verbose

Whether or not running in verbose mode

false

false

MEDIUM

camel.component.nats.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.

false

false

MEDIUM

camel.component.nats.autowiredEnabled

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

false

MEDIUM

camel.component.nats.useGlobalSslContextParameters

Enable usage of global SSL context parameters.

false

false
