Documents of products collection are intentionally designed to be more complex and larger than accounts - I want to see what happens, what is the performance penalty mainly, once individual documents are stored on multiple database pages. In Postgres, page size is 8 KB by default - in practice, the goal is to have at least 4 rows stored on a single page, so every record that is larger than 2 KB is put on two or more disk pages. It obviously reduces performance for both writes & reads - more disk pages to read from and write to. In Mongo it works slightly differently in details, but essentially in the same vein - larger documents are stored on more than one page, degrading performance for all operations. In both cases we are about to see - how much exactly.

With a built-in lightbar, a three-mode camping light that packs into the top of the power station, 768Wh and 1200W rated power, and enough ports to plug in up to 10 devices at once, the Solix C800x makes a great companion for off-grid living. You can charge it up with a traditional outlet, a solar panel (sold separately), or a car port for convenience. And since it's just 24 pounds, it's easy to take with you on the move.
