wildcard search in ?all

So, trying to mimic some really expressive behavior that grafana uses. They allow you to track metrics with keys like: a.b.c.d.e and you can do analytics/querying based on searches of a.b.*.d.e. Note, using dots instead of slashes wouldn't change how this is implemented.

A real world scenario around this:

myapp.*.logins

where the convention used is myapp.version.logins.

That query (services.com/myapp.*.logins?all=true) allows you to get all login event metrics across all versions/deploys and can compare. A/B testing and a lot of things would be enabled by this.

I'd imagine we would just pass the raw string to the db adaptor and let them figure out how to parse/support it. For the file-db adaptor, should be a simple change of the filter to use a regex. Something along the lines of key.match(new RegExp('^' + options.pathname.replace('*','.*')))

Segui la gestione della query ?all e dell’adattatore file-db per individuare dove viene applicato il filtro di pathname. Verifica come l’adattatore riceve il pattern della chiave grezzo, quindi verifica che una query come myapp.*.logins corrisponda alle chiavi tra le versioni mantenendo il comportamento esistente per le chiavi esatte.
