A developer has identified a method in an Apex class that performs resource intensive actions in memory by iterating over the result set of a SOQL statement on the account. The method also performs a DML statement to save the changes to the database.

  • A. Use the @ReadOnly annotation to bypass the number of rows returned by a SOQL.
  • B. Use partial DML statements to ensure only valid data is committed.
  • C. Use the System.Limit class to monitor the current CPU governor limit consumption.
  • D. Use the Database.Savepoint method to enforce database integrity.

C. Using the System.Limit class to monitor the current CPU governor limit consumption can indeed help you keep track of your governor limits during execution. It's a valuable debugging and monitoring technique. D. Using the Database.Savepoint method to enforce database integrity is a valid approach to ensuring data consistency and integrity within a transaction. Savepoints allow you to set points within your transaction and roll back to those points if necessary.
