The TAC mode is actually a variant of the TCC mode. Just as the name implies, the TAC mode is called automatic rollback. As compared with the TCC mode, the user doesn’t have to concern about how to write the rollback method at all. and then it can reduces user development volume and is entirely transparent to users.

  • TAC Mode is only suitable for Relational Database.

  • TAC Mode will intercept the user’s SQL statement to generate reverse rollback SQL, and the compatibility of SQL will also be a ordeal.
