New Database/Airtable Block question

Hello everyone, i’m in the middle of a very important task, i need to reduce my API calls to Airtable database.

I’m then exploring new way to access data and i saw for the first time this new (to me) block:

May I ask if this block performs just one API call to Airtable (maybe using the filter options that Airtable provides), or it’s a sum of two different API calls (one for looking at the destination list and then to filter the list based on one value)?

Thank you very much, hope the question was clear!

That would likely be one api call. If the objective is to reduce API calls then unless the data is changing in the table, I would save the information in a local table to self-cache information.
