Hello, I have a use case where I need to merge a large number of small pdf document (hundred of thousands) into one pdf document. Currently I am using the method: org.apache.pdfbox.util.PDFMergerUtility.appendDocument(destination, source); for all the source documents, not directly mergeDocuments() method in the same class because I need to also add some bookmarks. Finally I save the document.
Is it a better way of doing this with a lower memory footprint? I tried importing each page from the source documents by using the method PDDocument.importPage() but still throws errors in version 1.8.2. When I call PDDocument.load(File) the whole document is loaded in memory? If so, it means that saving the generated pdf after merging a subset of documents and then reloading it would not decrease the memory use anyway ... Could somebody point me to the right way of doing this? Thanks, Mihaela
