What action should be taken to ensure successful data loading of 5 million donation records?

To successfully load a substantial number of donation records, such as 5 million, temporarily disabling the TDTM (Table Driven Trigger Management) Trigger Handlers is a strategically sound approach. TDTM is utilized to manage data processing through triggers to ensure that the data adheres to the organization’s business logic and validation rules. However, when dealing with vast volumes of data, these trigger handlers can cause performance issues or errors if they validate data inconsistently or execute complex logic that may not be necessary during a bulk data operation.

By disabling the TDTM Trigger Handlers, you allow the data to be loaded without the overhead introduced by these triggers, which may lead to faster processing and reduce the risk of failure due to trigger-related errors. Once the data upload is complete, you can re-enable the trigger handlers to ensure that the business processes are then applied to any new or updated records going forward.

Other options provided, such as creating an Apex Test Class or deploying a custom Apex Class, may not directly contribute to mitigating issues related to bulk data loading. Disabling data validation rules is also not advisable because it may lead to a compromise in data integrity. Properly managing the data load process while ensuring that any business rules and validations are applied post-load
