Answer 1

Assuming a rolling hour window:

Maintain a list of when actions were done.

Each time you want to do your action, remove all in the list not within the hour.

If there are fewer than 1000 then do the action and add a record to your list.

Assuming hourly:

Create a proxy method and a variable that is incremented for every action, and reduced to zero on the hour.

Do your action if the counter is < 1000.
