Hi Gerrit, thanks for your generous offer to sponsor the requested feature. I am ashamed to confirm it’s been a long time since this issue has been opened and not closed yet. You are asking how much money will be required to get this fixed. I’m not sure after all. Maybe I would rather ask for 3, 4 weeks of “leisure time”, or – even better – get a proposal into my hands how this could be resolved without compromising backward conformance.
Some more details: The current storage layout per node has been fixed to 16 bytes. One byte (8 bits) is reserved for the namespace reference. The other 15 bytes (minus a few unused bits) are reserved for other references and flags. We could extend the storage to 24 or 32 bits. As a result, the central database main table would get larger, so this would affect both old databases (that need to be imported) and the overall performance of the system. If we decide to go this step, we could indeed overcome various of the current limitations. Any volunteers out there who are ready for the challenge?
