The Zip Data Format is a message compression and de-compression format. Messages marshalled using Zip compression can be unmarshalled using Zip 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. It facilitates more optimal use of network bandwidth while incurring a small cost in order to compress and decompress payloads at the endpoint.

To specify a specific compression Level use java.util.zip.Deflater settings. The possible settings are |
Marshal
In this example we marshal a regular text/XML payload to a compressed payload employing zip compression (Deflater.BEST_COMPRESSION) and send it an ActiveMQ queue called MY_QUEUE.
from("direct:start").marshal().zip(Deflater.BEST_COMPRESSION).to("activemq:queue:MY_QUEUE");
Alternatively if you would like to use the default setting you could send it as
from("direct:start").marshal().zip().to("activemq:queue:MY_QUEUE");
Unmarshal
In this example we unmarshal a zipped payload from an ActiveMQ queue called MY_QUEUE to its original format, and forward it for processing to the UnZippedMessageProcessor. Note that the compression Level employed during the marshalling should be identical to the one employed during unmarshalling to avoid errors.
from("activemq:queue:MY_QUEUE").unmarshal().zip().process(new UnZippedMessageProcessor());
