Zip DataFormat Page edited by Claus Ibsen Changes (1) 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. {info:title=About using with Files} The Zip data format, does not (yet) have special support for files. Which means that when using big files, the entire file content is loaded into memory. This is subject to change in the future, to allow a streaming based solution to have a low memory footprint. {info} h3. Options ... Full Content The Zip Data Format is a message compression and de-compression format.

About using with Files The Zip data format, does not (yet) have special support for files. Which means that when using big files, the entire file content is loaded into memory. This is subject to change in the future, to allow a streaming based solution to have a low memory footprint. Options Option Default Description compressionLevel null To specify a specific compression Level use java.util.zip.Deflater settings. The possible settings are            - Deflater.BEST_SPEED           - Deflater.BEST_COMPRESSION           - Deflater.DEFAULT_COMPRESSION If compressionLevel is not explicitly specified the compressionLevel employed is Deflater.DEFAULT_COMPRESSION 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());  Dependencies This data format is provided in camel-core so no additional dependencies is needed.
