0. The timing of the call is wrong, what should I do if the data is fetched wrongly? Obviously there is a problem with our interface evaluation communication .
0. Whoever sends the message, who provides the data. Avoid checking back after receiving the message .
1. I told you how much has changed, and I can't directly reject the demand. .
How can demand be unreasonable (in a product-driven company)
What we have to consider is what are the risks of such a scheme ? What error will it cause? What complexity will it lead to the system .
Do you mean that your technical level is not enough ? Is it possible to find someone with a high level of ability?
- You don't have time, the schedule can't be scheduled. Then let someone else do it.
- If you say you can't do it, that means the technical level is not enough.
1. Adjust the interface, yes. Not to let him tune.
But it is reasonable and unreasonable to make my door. (Just now he said that calling us to make judgments is very problematic.)
It is obviously not only his responsibility to cause losses in the future, but also our responsibility and accountability for the failure of our assessment and communication problems . (Cannot push the blame.)
Therefore, for each application that accesses our interface, we must help him evaluate (hang us to make judgments) whether it is reasonable or not . Will there be a problem .
0. Ask more and listen to the ideas of other product managers. We can’t create products with so much data? ? ?
0. We are the middle and Taiwan provider, providing data support to help you complete your needs.
1. Billing?
How do you remember the fee? What data to use to remember the fee? (need to be clear)
We have this data, but what if you make a mistake ? What if the timing of the call is wrong ?
How can we help you fulfill this requirement?
2. How can we help him and fulfill his needs.
- We have this data, but the timing of their calls is not right.
- Can this data meet his needs?
- They call us wrong, how to solve it for the other party
You have to figure this out and talk about it all over again. . .
2. Storage (hbase, zk, redis, db) tp availability should be increased
Core business, to increase the number of times. At most 1 time per minute
rpc tp availability to increase
3. Aren't you just looking for death?
Do you know how much money you lose if you write a wrong line of code?
Can't use it, how many users go to ali.
When it's done, Double 11 will be on the big screen.
Deleted one more line of code and made a low-level mistake. Affects the use of coupons.
4. Think more about middleware. I saw your group. I thought you did it on purpose.
5. Why don't you watch the police? Why do we still spend time matching?

5. Bo: This upstream is more clear. My side is only the middle. To store this data, they may have a better way.
