 This is probably useful for streaming, but perhaps less so for a one-off static query?
 
 The next `result-mode` is similar but shows the table as a change log (a concept very familiar to me from the [stream-table duality](https://www.michael-noll.com/blog/2018/04/05/of-stream-and-tables-in-kafka-and-stream-processing-part1/)). The results are still shown on an updating and interactive screen.

 (_If you are wondering how there is an `UPDATE` operation in a simple `SELECT` then take a close look at the `FROM` clause of the SQL being run . The `name` value `Bob` appears twice, and so the aggregate state change from a `COUNT` of 1 to 2_)

 For a "normal" result display (in a tabular view, no change log, just the final state) we set another parameter, `runtime-mode`:

 I want to start digging into how Flink's view of everything being a stream—just [bounded or unbounded](https://flink.apache.org/what-is-flink/flink-architecture/#process-unbounded-and-bounded-data)—works alongside the SQL semantics of a `TABLE`.

 In the root of the Flink directory (from which I launched the cluster and the SQL Client) is a folder called `log`. In there I looked at the recently changed files and searched for `IllegalArgumentException` which yielded the following in `flink-rmoff-standalonesession-0-asgard08.log`:

 Remembering the Flink Web UI that I saw [last time](/2023/10/05/learning-apache-flink-s01e03-running-my-first-flink-cluster-and-application/) I headed over to see what I could see there. A whole lotta `CANCELED`!

 Via this you can get to the Job Manager and Task Manager logs (just as I did from the `log` folder, but this time through the Web UI). It also reminds me that I still need to figure out where these components come in the runtime architecture 😅
