I am using PDFBox 2.0.23 to merge a large number of single page searchable PDF
files. As these files are stored in the cloud, and to make a copy of
PDFMergerUtility::optimizedMergeDocuments passing in sourceObject other than a
File or InputStream.
In support of cloud environments, I am requesting an enhancement to PDFBox
allowing one to pass in an object that implements an interface such as the
Resource in the SpringFramework.
In merging a large number of files, and frequently get OOM. An examination in
VisualVM indicates a large number of ScratchFile objects.
Looking for suggestions on how best to merge a large number (say 100K) of
searchable PDF files generated during OCR (i.e. image + text).
Thanks
