On what information do you base your opinion that the engineers at uber are very talented?
So far what i have seen, the only thing Uber is talented at is violating local laws and then throwing sacks of money at it to pay fines or whatever. (and inflating their own (bubble)value, but probably not many people agree with that)
Seeing their blogs mysql-> postgres followed by a postgres -> mysql migration, doesn't give me the idea they are very talented (they still might be, but so far no data has proven me this). Talented would be to forsee these issues and to have avoided encountering them at all. At least that would be my definition of very talented.
- debaserab2 10y agoI'm not sure what anything you said has to do with their choice of database.
- thinkMOAR 10y agoThen with your own reasoning, i'm also not sure that is worth a comment of yours. I clearly indicate their recent changing of db software twice to avoid issues (experts could solve) is an indication one in my eyes is not very talented.
- debaserab2 10y agoActually no, you didn't clearly say that at all. How do the experts solve the fact that Postgres' rewrites entire indexes on row updates?
- thinkMOAR 10y ago"Seeing their blogs mysql-> postgres followed by a postgres -> mysql migration" this is not clear to you? Perhaps a visit to an optician is in your best interest. And why do you make the assumption, i'm a postgresql expert to answer that question. Though others did, so if you would have bothered to read the other thousands of comments on the matter. You would not have needed to ask this question, PostgreSQL Heap-Only-Tuples (HOT) from: http://use-the-index-luke.com/blog/2016-07-29/on-ubers-choice-of-databases http://use-the-index-luke.com/blog/2016-07-29/on-ubers-choic...
