How does tsDecl fetch raw data?


Let’s say I have 10 years of raw data stored in some time series type. Let’s say I’m evaluating a tsDecl metric on that data for 1 day.

Which will the platform do?

  1. Fetch 10 years of data, normalize it, return the portion of the eval spec
  2. Fetch 1 day of data, normalize it, return it

In case you found out something, I would like to know if one can choose the normalizer in this context, and how.
