What are Governor Limits in Force.com Custom App Development?
Governor Limits in Force.com Custom App Development are Salesforce’s way of forcing you to write efficient, scalable code.
The limits count for each Apex transaction. For Batch Apex, these limits are reset for each execution of a batch of records in the execute method.
This table lists limits for synchronous and asynchronous Apex (Batch Apex and future methods) when they’re different. Otherwise, this table lists only one limit that applies to both synchronous and asynchronous Apex.
