I have one catalogue of approx. 100,000 images (+ a much smaller one) and a colleague of mine has a catalogue of almost 200,000 images. The (100,000) catalogue itself is 750 megabytes whilst the images themselves amount to something over 1.5 terabytes.
300,000 raw files is not the problem. a catalogue of over one TB may well be too much for the computers ram and cache to handle.
As I understand it, the catalogue is based on a SQL database. Whilst these are fairly small in structure, they do need a bit of working area to fulfil their functions.
I think the upper limit on Lightroom to handle data, taking into account the transition from 32 bits to 64 enabled a huge number of database locations, probably into several millions, but the computer hardware would not be able to stretch that far.
I used to maintain an Access Database, (SQL) which contained over 7 million entries, but the computer system to drive it was far more powerful than any consumer desktop.
I would stop at 100,000 and give serious consideration to creating a new catalogue, the searching will be faster as will the backups.
I forgot to mention the previews, on my 7,000 image catalogue they amount to 3.5 GB. I do not have any previews on the 100k catalogue, I delete them to save space and rebuild them if needed. (Its an overnight job rebuilding).
