Stitching of Event data with Profile enabled datasets takes longer time

Hi Team,

I have an event data set that was created after the Profile dataset(both are profile enabled and stitched with a common id).

Now it has already 48 hrs passed but the event data is not stitched with the profile.

Both are having 1.3m records and are loaded by query service.

As the monitoring screen shows all status success.

Any suggestions on what can be the issue and how we can understand the process going on inside the profile store?

Thanks
