Subject Generating large spreadsheets and streaming responses
Date Wed, 21 Mar 2018 17:54:58 GMT

I was wondering, are there any solutions in POI for streaming large
spreadsheets over an HTTP response?  I have a JAX-RS backend that I
currently seed with POI.  I use StreamingOutput to stream the worksheet to
the client.  The problem is that this approach requires the entire
spreadsheet to be created in memory first and then sent over the wire.  I'd
like to be able to send it out in a stream for performance reasons, as well
as getting the HTTP response sent out quicker.
