Correct. Structured streaming needs to be considered as a table with append

correct; The key idea in Structured Streaming is to treat a live data stream as a table that is being continuously appended. This leads to a new stream processing model that is very similar to a batch processing model. You will express your streaming computation as standard batch-like query as on a static table, and Spark runs it as an incremental query on the unbounded input table. Let’s understand this model in more detail. https://spark.apache.org/docs/latest/structured-streaming-programming-guide.html
