Splitting a stream from a servlet
All, I have a camel servlet that is consuming an XML stream. I currently have
it splitting that stream successfully. The problem is that I need to split
it multiple times. There are 2 sections in the stream that I am interested
in. Once I have those split out, I intend to forward them as JMS messages
via HornetQ. Right now just to get it working im trying to send the output
of the split to file. This is my current config. It will only split using
the first split tag.
<route>
<from uri="servlet:///input" />
<split streaming="true">
<tokenize token="mules" xml="true" />
<to uri="file://c:/dev/servlet-output-mules" />
</split>
<split streaming="true">
<tokenize token="donkeys" xml="true" />
<to uri="file://c:/dev/servlet-output-donkeys" />
</split>
</route>
Is there a way to split the stream multiple times without loading the entire
document into memory? Thanks for any help. I am using Camel 2.9.2.

Do you really have such big messages that they cannot be loaded into
memory once?
If you convert the message to a String, then you can multicast and use
2 splitters.
If not then you can split it once, and then implement logic that
splits into both donkeys and mules.
And then do a content based router, to route donkeys and mules differently.
Alternatively you can store it in a temporary off memory store such as
a disk, and then split it from disk, which can be read 2+ times etc.
