Chartmat uses a smart way to determine when it should cache boards & data, most of the time this is something you shouldn't worry about but you might wonder why your embed doesn't get updated immediately. These are the rules we follow:
- Private boards never get cached
- When you are logged in data is never cached
- Public boards and embeds get cached for 10 minutes
In other words data is always real time apart for public boards.
This is done in order to avoid hitting the Google Sheets API hundreds of times in a minute, a problem which can easily happen when a board is public.
Caching is done directly at a CDN level, we don't store any data directly in our server or database and it's deleted automatically once the 10 minutes have passed.
