How to gzip response of camel restet

[bhavishya goyal]

Hi,

I have camel restlet component which send large data of around 500K records
in json. if i send without zip it take around 20 min. I though to zip my
response so i have include content encoding header like this but in this
case request is getting failed

<get
uri="/getAnalyticsReport?synchronous=true&amp;streamRepresentation=true"
bindingMode="off">
<to uri="direct:analyticsReport" />

</get>

<route id="analyticsReport">
<from uri="direct:analyticsReport" />
<bean ref="algo" method="fetchInstrumentValues" />
<setHeader headerName="Exchange.CONTENT_ENCODING">
        <constant>gzip</constant>
    </setHeader>

</route>

I tried with other way but still no  success

<route id="analyticsReport">
<from uri="direct:analyticsReport" />
<bean ref="algo" method="fetchInstrumentValues" />
 <setHeader headerName="Exchange.SKIP_GZIP_ENCODING">
        <constant>false</constant>
    </setHeader>
    <setHeader headerName="Exchange.HTTP_CHARACTER_ENCODING">
        <constant>UTF-8</constant>
    </setHeader>


</route>

my function returns string of json data.

these are response header
