How it usually goes for me.

I ask business how often should something be updated - they say “real time” (not going into details what real time means really) - it is hard to explain processing all data all the time so everything is fresh takes forever….

After couple of months it turns out they never ever open their “super important dashboard” or do it once in 6 months.

Great after a year of bogging down everything I can clean up and make jobs run once a day instead of once a minute because now it is acceptable.

Why take the unspecific "real time" answers as gospel? Just propose daily initially (or weekly or monthly), listen to their protests, and see if there are good reasons why it needs to be more often. Then pick a suitable interval that fulfills their needs and that you can guarantee. If you offer pink fluffy unicorns for free, people will always pick them, without thinking.

Well it is not clear from my initial post but I do propose daily or whatever else than just "every SeCoND BecAuSE we NeeD iT NOW!!!" but people that are clicking the system right away expect stuff to happen "right away" - and any amount of explanation does not work.

Bonus points for trying to explain you want to implement "eventual consistency" - keep in mind I have added {“real time” (not going into details what real time means really)} in text to indicate that I am not some junior whining around but someone with deep understanding of computing...
