附一个国外用户的解答：

There is no out of the box solution. But you can do the following:

  1. Get the data_length and index_length for the tables the user owns with show table status (This is the amount of space the data files use in the file system)
  2. Sum up these numbers for all databases
  3. If the limit is reached, remove for example INSERT privileges for that user, so he can not insert new data anymore.

But keep in mind that removing data from an InnoDB tables will not free up space in the file system. So if your user reached the limit, he can not do anything against it. (Except dumping all InnoDB tables, dropping them and reimport them)
