The LZF Data Format is a message compression and de-compression format. It uses the LZF deflate algorithm. Messages marshalled using LZF compression can be unmarshalled using LZF decompression just prior to being consumed at the endpoint. The compression capability is quite useful when you deal with large XML and Text based payloads or when you read messages previously comressed using LZF algotithm.

Description

usingParallelCompression

boolean

false

Enable parallel compressor implementation which can encode (compress) content using multiple processing cores: concurrent compression works on chunk-by-chunk basis (64k max chunk size) so megabyte-sized content can be processed very efficiently.

Marshal

In this example we marshal a regular text/XML payload to a compressed payload employing LZF compression format and send it an ActiveMQ queue called MY_QUEUE.

 

from("direct:start").marshal().lzf().to("activemq:queue:MY_QUEUE");

 

Unmarshal

In this example we unmarshal a LZF payload from an ActiveMQ queue called MY_QUEUE to its original format, and forward it for processing to the UnGZippedMessageProcessor.

 

from("activemq:queue:MY_QUEUE").unmarshal().lzf().process(new UnCompressedMessageProcessor());

 

Dependencies

To useLZF compression in your camel routes you need to add a dependency on camel-lzf which implements this data format.

If you use Maven you can just add the following to your pom.xml, substituting the version number for the latest & greatest release (see the download page for the latest versions).

 

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-lzf</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>
