There are 3 important parameters: `bucket_span`, `query_delay`, and `frequency`

`bucket_span` is the analytics aggregation interval  
`frequency` is how often the data is queried via the datafeed  
`query_delay` is the total offset (from "now")

In other words, having a `query_delay` of `1d` doesn't make the query more expensive or the time range bigger. It is purely a lag behind real-time.
