    What is heap size, and what is its limit for asynchronous and synchronous calls? When the heap size limit is exceeded, how can you resolve that issue in Salesforce?

    Heap size is the size of the temporary storage of your data while executing your code in synchronous mode. All of your global variables get stored on the heap. For asynchronous mode, the heap size limit is 12 MB, and for synchronous mode, the heap size limit is 6 MB.
