Also worth noting, modifying two tables within a transaction can be a vector towards deadlocks if another procedure or query modifies the same two tables, but in a different order.

Agreed. You can run it as a push or a pull. It'll be the same. Probably, just as a general precaution, I'd run it as a pull, scheduling it from...

The differences in load is likely the differences in behavior (not necessarily, but, you know how it goes). Those settings were just a couple of examples. I'd examine both sets...

OK. Most of the work then is going to be with the structures you're building. It's a good idea to know that there are system views (frequently called tables) that...

I'm not familiar with the app, so no help there.

When you say you don't see it in your QA environment, my inclination would be to first ask what differences are...

That's going to be tough. We have to define what you mean by "most common" because it's very function dependent. Are you developing a database for an organization? Then the...

Great to see all the hams.73 to you all

This fight, like so many others, does come down to ignorance. We have to constantly educate ourselves and others.

Trace can do pretty much all you're looking for. It's just going to put a much heavier load on the system while it collects the data. Also, it's horrific at...

You're going to blow it out of the park Brandie. Relax and have fun with it.

Sorry, I'm confused. "update stats on the table with...

Time to employ extended events and capture the query metrics. That's the single best thing you can do. Identify how long each query takes, how frequently they are called,...

The same as with any performance problem, you have to gather metrics to identify where the issues lie. I can't tell you what the problem is because other than high...

That looks OK to me. Does it work?

Check your databases. Sounds like one is corrupted. Run DBCC CHECKBD on them (during off hours, this is a fairly intensive query).

First thing I'd do is understand if you're doing a lift & shift and just moving to Azure VMs, or, if you're implementing Azure SQL Databases or Azure Managed Instances....
