var defaultIsolationLevel: Int

Default transaction isolation level. If not specified, the database-specific level will be used. This can be overridden on a per-transaction level by specifying the transactionIsolation parameter of the transaction function. Check Database.getDefaultIsolationLevel for the database defaults.
