Modify percision for existing data

Is there a way to set precision on a specific database? Currently I have a database that has been working for about a month and queries that are greater then a few weeks are timing out which I suspect is due to number of entries which could be cleaned up if precision was in minutes or seconds.

Thanks!

The precision shouldn’t make a huge difference in this case.

Also, the time precision is only controllable on an individual write level. When it’s on disk, everything (all timestamps) is int64s.

I’m curious to know how much data you’re querying. The number of series and overall points could be causing the timeouts.
