With the new Winter ’21 release, salesforce makes it much easier to detect what is a current running context by means of Request.getCurrent().getQuiddity() method. This is great, thank you, salesforce.
//Get info about the current request Request reqInfo = Request.getCurrent(); //Universally unique identifier for this request //Same as requestId in splunk or REQUEST_ID in event monitoring String currentRequestId = reqInfo.getRequestId(); //enum representing how Apex is running. e.g. BULK_API vs LIGHTNING //Use this with a switch statement, //instead of checking System.isFuture() || System.isQueueable() || ... Quiddity currentType = reqInfo.getQuiddity();
