we're using ujson in Monasca for serialization all over the place. While
changing it to any other alternative is probably a drop-in replacement,
we have in the past chosen to use ujson because of better performance.
It is of great importance, in particular in persister. Current
alternatives include orjson  and rapidjson . We're going to
measure which of them works best for our use case and how much faster
they are compared to standard library module.
Assuming there is a significant performance benefit, is there any
preference from requirements team which one to include in global
requirements? I haven't seen any distro packages for any of them.
