I have to update 50,000 records, and I am worried that a trigger or flow will fire and do something unexpected to those records. What is the standard way to handle 'mass updates' without triggering all our automations?
I have heard of using custom metadata to 'turn off' flows, but that seems dangerous. Is there a better architectural way to flag records as 'in mass update' so the automation knows to skip them?
Implementing a hierarchical bypass setting or a dedicated system flag within your automation entry criteria provides the most secure and scalable method for preventing unintended side effects during mass record updates.

You should adopt a robust bypass mechanism that handles record-level exclusions to avoid the risks associated with global toggles.
- Create a custom hierarchical settings object to define bypass users or profiles
- Add a logic gate in every trigger or flow entry criteria checking this setting
- Use a specific system context flag during your data import script
- Test the bypass logic in a sandbox with a representative subset of records
- Audit the logs for any unintended side effects after the mass update completes
Stop looking for a magic switch and implement a bypass custom permission or a hierarchy-based bypass setting. Updating 50,000 records requires a controlled batch execution environment, not a global override that risks your data integrity during the window of operation.
I recall a nightmare scenario years ago involving a recursive trigger on a Case update that crashed an entire org during a scheduled migration because someone forgot to check for a null context. It taught me that relying on custom metadata to toggle production logic is playing with fire.
We ended up refactoring the entire automation layer to respect a static boolean bypass variable handled in a trigger framework, which was much cleaner. Now, I never move data without verifying that the apex handler can be bypassed via a service class method.
Bypassing automation via global custom metadata is essentially a digital version of playing Russian Roulette with your production data. If your architecture is so brittle that you have to turn off the engine to perform a standard update, then the issue isn't the data, it's the design. Better to implement a standard bypass field or a custom permission check, as these allow you to safely ignore specific records without leaving the entire system wide open to corruption.
Using a system flag to ignore records is far superior to disabling flows globally because it provides granular control. Global metadata toggles work if you have a single monolithic process, but they fail when you need to run concurrent updates or partial migrations. A bypass flag on the record level or a custom permission allows you to segment your data processing without risking system-wide outages or inconsistent application state during your maintenance window.
The issue with using custom metadata for mass updates is that it creates a global state change, which introduces risk to all users in the system simultaneously. When you disable a flow to accommodate an update, you are effectively turning off critical business logic for everyone else, which is rarely acceptable in an enterprise environment.
Instead, consider the implementation of a Bypass Framework. This typically involves a service class or an entry criteria component that checks for the presence of a specific user or a temporary custom field on the record. By setting an 'IsMassUpdate' field to true during your bulk operation, you can configure your automation entry criteria to evaluate this field. If the flag is set, the automation simply skips execution for that record.
This approach is significantly safer because it isolates the logic suppression to the records you are specifically touching. It ensures that standard user transactions continue to flow through the system unimpeded while your backend process remains shielded from triggering side effects. It is a more mature way to handle technical debt and data hygiene. Ultimately, you want to move away from binary switches that affect the entire org and toward a logic gate that respects the current context of the record being processed. This keeps your system stable, audit-friendly, and maintainable as your volume of data continues to scale upward over time.
