When loading a large volume of data, such as 5 million donation history records, into Salesforce, it is

essential to temporarily disable TDTM (Trigger Handler Framework) to ensure the data load is

successful. TDTM triggers can slow down or interrupt the data load process due to the large volume

of records being processed.

Steps:

Go to Setup > Custom Metadata Types.

Select "Trigger Handlers."

For each trigger handler, uncheck the "Active" checkbox to temporarily disable it.

Perform the data load using Data Loader or another data import tool.

Once the data load is complete, re-enable the TDTM Trigger Handlers by checking the "Active"

checkbox for each trigger handler.
