GZip Deflater DataFormat

Available as of Camel version 2.0

The GZip Deflater Data Format is a message compression and de-compression format. It uses the same deflate algorithm that is used in the Zip data format, although some additional headers are provided. This format is produced by popular gzip/gunzip tool. Messages marshalled using GZip compression can be unmarshalled using GZip 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 gzip tool.

This dataformat is not for working with gzip files such as uncompressing and building gzip files. Instead use the zipfile dataformat.

Options

The GZip Deflater dataformat supports 1 options, which are listed below.

Name Default Java Type Description

contentTypeHeader

false

Boolean

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.

Marshal

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

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

Unmarshal

In this example we unmarshal a gzipped 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().gzipDeflater().process(new UnGZippedMessageProcessor());

Dependencies

This data format is provided in camel-core so no additional dependencies is needed.
