camel-stream-kafka-connector sink configuration

Connector Description: Read from system-in and write to system-out and system-err streams.

When using camel-stream-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-stream-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.stream.CamelStreamSinkConnector

The camel-stream sink connector supports 10 options, which are listed below.

Name Description Default Required Priority

camel.sink.path.kind

Kind of stream to use such as System.in or System.out. One of: [in] [out] [err] [header] [file]

null

true

HIGH

camel.sink.endpoint.encoding

You can configure the encoding (is a charset name) to use text-based streams (for example, message body is a String object). If not provided, Camel uses the JVM default Charset.

null

false

MEDIUM

camel.sink.endpoint.fileName

When using the stream:file URI format, this option specifies the filename to stream to/from.

null

false

MEDIUM

camel.sink.endpoint.autoCloseCount

Number of messages to process before closing stream on Producer side. Never close stream by default (only when Producer is stopped). If more messages are sent, the stream is reopened for another autoCloseCount batch.

null

false

MEDIUM

camel.sink.endpoint.closeOnDone

This option is used in combination with Splitter and streaming to the same file. The idea is to keep the stream open and only close when the Splitter is done, to improve performance. Mind this requires that you only stream to the same file, and not 2 or more files.

false

false

MEDIUM

camel.sink.endpoint.delay

Initial delay in milliseconds before producing the stream.

null

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.readTimeout

Sets the read timeout to a specified timeout, in milliseconds. A non-zero value specifies the timeout when reading from Input stream when a connection is established to a resource. If the timeout expires before there is data available for read, a java.net.SocketTimeoutException is raised. A timeout of zero is interpreted as an infinite timeout.

null

false

MEDIUM

camel.component.stream.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.stream.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

The camel-stream sink connector has no converters out of the box.

The camel-stream sink connector has no transforms out of the box.

The camel-stream sink connector has no aggregation strategies out of the box.
