Off-topic, but do you know how Tika compares to other pdf parsing libraries? I was very unimpressed by pdfminer.six (what unstructured uses) as the layout detection seems pretty basic, it fails to parse multi column text, whereas MuPDF does it perfectly

Currently I'm using a mix of MuPDF + AWS Textract (for tables, mostly) but I'd love to understand what other people are doing

Tika uses PDFBox under the hood, using its built-in text extractor (which is "ok"). If you're looking for table extraction specifically, check out Tabula (https://tabula.technology) which is also built on top of PDFBox and has some contributions from the same maintainers. PDFBox actually exposes a lower-level API for text extraction (I wrote it!) than the one Tabula uses, allowing you to roll your own extractor - but that's where dragons live, trust me :)

I don't have scientific metrics but I've found the quality much better than most. It does a pretty good job to pulling data from text and tables.
