I am suffering with Salesforce apex LimitException issue. I am fetching thousands of records from few objects and putting it into the collection like Map. Now I have a requirement to generate JSON for same records which will be used for mobile devices to download data from Salesforce. When I tried to serialize those records by using System.JSON.Serialize() method; it is generating a huge JSON string and I am getting System.LimitException error because there will be more memory required than available space. I tried to catch that issue using try/catch block but here is a reference available which says that System.LimitException can’t be caught by Catch block. Referral URL:
I know that we can check heap size limit through Limits.getHeapSize() method. But is there any work around so that I can handle this issue from apex side. A code sample or some reference in this regard would be highly appreciated. Thanks in advanced.
