Solved How to achieve best performance?

I'm making plugin where people can claim chunks, but if they don't login for one amount of days the chunk will unclaim itself. I currently have a map of chunks and calendars (the calendar is when it's calculated to expire). The question is, what's the best way to remove the chunks? With potentially thousands of people claiming multiple chunks scheduling a task for each one seems very slow. What's the best way?

 

How many thousands of people are you expecting to claim chunks? I suspect you are perhaps greatly overestimating the amount your plugin will get used.

Anyway. Just have a map with a date/calendar and a collection of chunks. This way you can claim multiple chunks in the same moment. Then schedule a task every hour that removes all entries if their expiration date is exceeded.
Not performance intensive at all.

 

alr, thanks
