Chapter 206. LZF Deflate Compression DataFormat
Available as of Camel version 2.17
The LZF https://cwiki.apache.org/confluence/display/CAMEL/Data+Format[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.
The LZF Deflate Compression dataformat supports 2 options which are listed below.

Enable encoding (compress) using multiple processing cores.

Whether the data format should set the Content-Type header with the type from the data format if the data format is capable of doing so. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSon etc.
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.
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
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 https://cwiki.apache.org/confluence/display/CAMEL/Download[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>
