How many characters will be generated for id and/or sid?

[TokugawaTakeshi]

The following example from README.md does not make clear how many characters will be generated for id and sid.

model Session {
  id        String   @id
  sid       String   @unique
  data      String   @db.MediumText  // MediumText may be needed for MySql
  expiresAt   DateTime
}

I have experimentally knew that 30 characters is not enough.
How many will be enough?

Hi @TokugawaTakeshi,

I believe this is determined by the underlying database, and how it is configured.
