Why are there execution governors and limits in apex?
Execution Governors and Limits. Because Apex runs in a multitenant environment, the Apex runtime engine strictly enforces limits so that runaway Apex code or processes don’t monopolize shared resources. If some Apex code exceeds a limit, the associated governor issues a runtime exception that cannot be handled.
Why are there run time limits in apex?
Because resources are shared in a multitenant platform, the Apex runtime engine enforces some limits to ensure that no one transaction monopolizes shared resources. Your Apex code must execute within these predefined execution limits. If a governor limit is exceeded, a run-time exception that can’t be handled is thrown.
How to avoid heap size limit in apex?
// Perform SOQL query outside of the for loop. // This SOQL query runs once for all items in Trigger.new. Use SOQL for loops to operate on records in batches of 200. This helps avoid the heap size limit of 6 MB.
Is there a cpu governor limit on Salesforce?
After some research, I found out that the Salesforce platform imposes a CPU usage governor limit to any given execution context, which is approximately 10 seconds. It means that Apex Code, declarative tools or a combination in a transaction, must not exceed a ~10-second limit.
What’s the maximum execution time for static apex?

What’s the maximum number of rows an apex class can insert?
The maximum number of rows that can be inserted, updated, or deleted, in a single, synchronous Apex test execution context, is limited to 450,000. For example, an Apex class can have 45 methods that insert 10,000 rows each. If the limit is reached, you see this error: Your runallTests is consuming too many DB resources.
