> With the addition of continuous file monitoring, apart from the {{StreamSource}} also the {{ContinuousFileReaderOperator}} uses a {{SourceContext}}. Given this, all the implementations of the {{SourceContext}} should be removed from the {{StreamSource}} and become independent classes.
> In addition, the {{AsyncExceptionChecker}} interface should be removed as its functionality can be replaced by the {{task.failExternally()}} method. This also implies slight changes in the source context implementations.
> Also in the {{trigger()}} method of the {{WatermarkEmittingTask}}, all the {{owner.getCurrentProcessingTime()}} could be replaced by the {{timestamp}} argument of that method. This will remove some of the calls to the {{getCurrentProcessingTime()}} which can be expensive.
