I've been seeing patterns in DLT process time in all my pipelines, as in attached screenshot. Each data point is an "update" that's set to "continuous". The process time keeps increasing until a point and drops back to what it's desired to be. This was not by any manual change and I don't see any correlation to hour of the day, or day of the week etc, and it doesn't look like due to data feed either. Has anyone seen this and could help me to understand why it's like this and how to optimize?

Thanks!
