Incremental Reflection Scheduling: Fixed Interval or Completion-Based?

1

Hi team,

In Dremio, I have a question regarding incremental reflection scheduling. Let’s say I have set the incremental reflection to refresh every 5 minutes starting at 10:00 AM. The first reflection begins at 10:05 AM and completes at 10:07 AM.

Will the next reflection occur at 10:10 AM (fixed 5-minute intervals) or at 10:12 AM (5 minutes after the previous reflection completed)? Does the reflection adhere to a fixed interval schedule, or does it depend on the completion time of the previous reflection?

Thanks in Advance.

@JoiceJacob 2 refreshes should not happen at the same time. So the second should start only after completion of the first if > 5 minutes. Which version of Dremio is this? Are you able to see in your jobs page filtered by refelction id, are you seeing a different behavior?
