DEFAULT_TRANSACTION_ISOLATION_LEVEL

The default transaction isolation level used by the MySQL driver implementation.

This value is set to Transaction.IsolationLevel.RepeatableRead, which ensures that if a transaction reads a row, the data in that row will remain consistent for the duration of the transaction. This prevents non-repeatable reads and strikes a balance between performance and data consistency in typical scenarios.

The default isolation level may be overridden if specific transaction requirements demand a different level of data consistency or concurrency control.
