Salesforce Customization Limits and Governor Limits
Salesforce enforces governor limits, caps on CPU time, SOQL queries per transaction, heap size and more, to keep one customer's code from degrading performance for everyone on its multi-tenant infrastructure. These limits are rarely a problem for simple customizations, but heavy custom logic triggered across bulk data operations, a mass import or a large batch update, can hit them and force a rewrite using asynchronous processing patterns.
We design Apex with bulkification in mind from the start, testing against realistic data volumes rather than the small record sets that pass in a sandbox but fail once a client's production data hits the same code path. Where logic can be expressed declaratively through Flow instead of Apex, we generally prefer that, since it reduces both the governor limit exposure and the long-term maintenance surface.
