A basic requirement : Add to the asynchronous mode of the GeneralWebConnector the ability to load data, the structure of which will be dynamically formed taking into account the structures of all files needed for loading.
The ticket #00017153 that I created in the technical support portal outlines the whole essence of the problem.
To summarize the idea briefly:
There is a task to quickly load a large number of JSON files with a dynamic structure. Previously used RESTConnector But for this task, it is not suitable because we need an asynchronous loading mode that increases the speed of loading data at times. The asynchronous mode is present in the GeneralWebConnector BUT this connector creates a data structure based on the first incoming json file, in contrast to the RESTConnector in which it is possible to customize the table structure based on the structure of all files needed to be loaded.
