[Corion]: Meh. SQL window functions would even make pagination easy/trivial (but not performant), as rank() over (partition by user order by timestamp) / 10 as page would give me a page number for each item, with 10 items per page.
[Corion]: Of course, the query performance for "all items on page 10" is likely worse than rank() between 100 and 109 , but if that means I can write 15 lines of SQL instead of needing to think about how to partition things and how to encode the page size...
[Corion]: ... that would be nice. But alas, I'm currently tied to SQLite as minimum implementation, and it doesn't implement window functions :-(
[Corion]: And I'm not aware of any other serverless SQL implementation that even reaches the capability of SQLite, not to mention surpasses it
