Geocoder (+other paths?) Cache #9

Closed Gordonei closed 2 years ago

Gordonei commented 4 years ago

Although the ambition of this service is to be stateless, a little bit of memorisation never hurt anyone. Headline is that before making expensive calls to the external geocoding service, we should check a local cache to see if we've asked for the same (or similar - pretty dangerous) address.

Cache entries should have some sort of defined lifetime, probably of the order of a few months, which is roughly the rate at which the very best geocoding services are likely making the most significant changes to their data.
