Thank you very much. From your suggestion, now I am more clearer on what we need do now. One more question, should we use ADF to ingest data via Http linked service to landing data into data lake, this is easy and simple implemention; or we use notebook to call API via then use dataframe to save as JSON, it seems to me that from API response to saving to JSON in the data lake is not that straight forward. Is there any good sample code for best practice implementation? Thanks ahead.
