How does bulk trigger work?
Bulkified triggers operate on all sObjects in the trigger context. Typically, triggers operate on one record if the action that fired the trigger originates from the user interface. But if the origin of the action was bulk DML or the API, the trigger operates on a record set rather than one record. For example, when you import many records via the API, triggers operate on the full record set. Therefore, a good programming practice is to always assume that the trigger operates on a collection of records so that it works in all circumstances.
Why bulkify code?
The benefit of bulkifying your code is that bulkified code can process large numbers of records efficiently and run within governor limits on the Lightning Platform. These governor limits are in place to ensure that runaway code doesn’t monopolize resources on the multitenant platform. The following sections demonstrate the main ways …
How many records does a trigger execute?
Triggers execute on batches of 200 records at a time. So if 400 records cause a trigger to fire, the trigger fires twice, once for each 200 records. For this reason, you don’t get the benefit of SOQL for loop record batching in triggers, because triggers batch up records as well.
Why use bulk design patterns?
We recommend using bulk design patterns for processing records in triggers. When you use bulk design patterns, your triggers have better performance, consume less server resources, and are less likely to exceed platform limits. The benefit of bulkifying your code is that bulkified code can process large numbers of records efficiently …
