I have a need to merge a couple thousand PDF's into one humongous PDF.
The old tool we use for PDF manipulation runs out of memory as it builds the
result PDF in memory, and only writes it out when done.
Can PDFBox do something more like streaming the output as it's built? or even
not load all the source pdf content streams until needed for output?
No + Yes, so you'll also run out of memory at some time.
If the huge job is for printing, then remove the structure tree from
each file, which is obviously not needed (it is for screen readers). You
should save somewhere and reload so that these are no longer in memory.
