I never claimed that changing database file formats was easy, but IBM had already increased the size limit once before from 4GB to 64GB. So obviously increasing it further could have been done. Unfortunately IBM leadership never saw Domino as anything more than a platform for small internal corporate IT applications so they didn't care about fixing the limitations; it was a total failure of vision. IBM didn't provide any tools for horizontal sharding either. We had to roll our own, which was a huge expense and made every part of the application far more complex. And it actually made reliability worse; because displaying incomplete data was not acceptable to customers, if any one database got corrupted then everything failed.
