[MarkLogic Dev General] Java XCC save query result to file

How critical to your app is it that the result is "streamed" ?
Is it always XML or is it sometimes text or binary ?

The xmlsh MarkLogic extension "get" command can be used as an example of writing the result items to a Java stream.

The "writeResult" method implements the guts of this command


The key is that a ResultSequence is an iterator of XdmItem.
Each XdmItem has a "writeTo" method.

There is no guarentee that this is "streamed" to my knowledge but it may well be.

Subject: [MarkLogic Dev General] Java XCC save query result to file


For some queries I'm using the xdmp:save() function to store results to file.   This will not always work because the MarkLogic server may not have access to the share location.

Instead the results will need to be saved by the application by streaming the ResultSequence returned from session.submitRequest(request) call.

Is there a preferred way to do this?

Thanks for your advice.  An example would be helpful if you have one.
