You don’t need an elaborate use case or huge data volumes to get started with Batch Apex. This section walks you through the development of a simple Batch Apex class that writes debug log entries as it runs. The class is submitted for execution using the Force.com IDE and monitored in the administrative Web user interface. Two more versions of the Batch Apex class are developed: one to demonstrate stateful processing and the other an iterable scope. The section concludes with a description of important Batch Apex limits.
