Which the best way to organize Reminders + Timers work?
I want to run a task with precision in a second.
As I understand I need to run a reminder with some interval. And each start of the interval will fire a timer to achieve a specific time. But which interval of reminder should I specify to achieve two goals:
Reminders are for approximate times (minutes), Timers are for precise times. You can create a robust solution by combining the two.
Obviously you will need something that initially creates the grain. You will also need persistent storage for the reminders. Then create a reminder AND a timer in OnActivateAsync().
In the reminder callback check for the existence of the timer, recreate it if necessary.
In the timer callback, make sure you call a grain method
private async Task SnapshotTimerFired()
{
var me = this.AsReference<IScoobyDoGrain>();
await me.DoSomethingForAScoobySnack();
}
by making the grain call the runtime will know that grain is alive and try not to deactivate due to memory pressure
