Root Cause Analysis
This incident was caused by a change made to the system where a new cluster replaced the existing cluster handling pipelines and this wasn't expected. This led to certain resources not being removed successfully from the infrastructure state file as previously thought, leading to delays in data processing.
There was no manual fix for this issue, the system just needed extra time to load the pipeline from the new cluster that was created unexpectedly. After a couple of hours, datasets were correctly synced.
