It’s really not about code is better or database it better, it’s mostly about locality: if you want to update thousands of records, you can’t pull those records into a separate process, update them there and then write back. So you put your code next to the data in the database. Stored procedures are just code deployed to a database container…

Sure you can, I've done it plenty of times. I'm genuinely curious why you think it's not possible.

The only reasons I can think of:

- you're rewriting a legacy system and migrate parts incrementally

- data compliance

- you're running a dangerous database setup

I try my best to avoid putting any business logic inside databases and see stored procedures only as a temporary solution.

Although I'm partial to a SPROC, I do not deploy them because I understand my colleagues might throw me from a window. But without going full tilt DB-as-the-application,

The DB can make much stronger guarantees about transactions and updates the closer that logic happens to itself. In the world of cloud computing, this can be a cost savings for ingress/egress too.

>> deploy them because I understand my colleagues might throw me from a window

Maybe throw your colleagues out the window instead if they don't know what they are talking about. I'm not anti/pro SPROC at all, but I am anti anti-reality. People that don't understand the vast differences in latencies between in process and out of process work should not exist in the industry.

Its possible but of course slow because of https://gist.github.com/jboner/2841832. Data locality matters a lot. Moving data around the network when it doesn't really need to be moved is heresy (unless performance doesn't matter, then who cares). Remember the computer doesn't care about your religion which says only this can do this and only that can do that.
