Question: Shopping setting information, such as address and phone name.
Don't underestimate this issue, this is a good way to increase the number of users and volume.
Several strategies and their respective advantages and disadvantages:
1. Traditional order submission requires setting information, and there is no default setting.
Advantages: Greatly weakened to dissuade users from coming up
Disadvantages: still need to be set, no matter which step is not bought before payment, this transaction is a failure
2. No address information is required before payment for panic buying products, but an account number is required. At the end of payment, you will be prompted to enter the address. If you do not enter a period of time, the order will be automatically abandoned.
Advantages: toss users after paying
Disadvantages: increased concurrency, of course, the concurrency design of the panic buying category is not a big problem. Malicious orders squeeze out normal users. Although account purchases are restricted, there are still problems.
3. IOC, users who snap up first sign up, and then select users on the server shuffle
Advantages: Although there is a high probability that malicious orders such as scalpers will also be selected, it can be said that they are much less and can greatly reduce concurrency
Disadvantages: users do not have the refreshing point of buying, of course, they can imitate buying, but users may not buy it
