* ♻️ refactor: initialize & store the config & cache structs as a constant (#486)
- initializes & stores the config & cache structs as a static constant.
- Pass the config & cache structs as a static reference to all the
functions handling their respective route.
* ⚡ perf: replace hashmaps with vectors for fetching & aggregating results (#486)
- replace hashmaps with vectors for fetching, collecting & aggregating results as it tends to be contigous & cache efficient data structure.
- refactor & redesign algorithms for fetching & aggregating results
centered around vectors in aggregate function.
* ➕ build: add the future crate (#486)
* ⚡ perf: use `futureunordered` for collecting results fetched from the tokio spawn tasks (#486)
- using the `futureunordered` instead of vector for collecting results
reduces the time it takes to fetch the results as the results do not
need to come in specific order so any result that gets fetched first
gets collected in the `futureunordered` type.
