Azure Data Explorer makes it possible to ingest data from external sources in many ways.
This can be done using eg. the database data connections, using programming code via the SDKs, or using the Azure Stream Analytics output for Azure Data Explorer.
Once a table is created and the incoming file/message format (CSV, JSON, etc) and data structure in the file or message stream are identified, a recurring theme is designing the table mapping for that format:

Here, a typical mapping for a JSON message is shown.
Testing a mapping can be cumbersome if you rely on that default ingest method involving those resources outside Azure Data Explorer.
Can this be done in a more easy way?
