@@ -550,6 +550,8 @@ The Dynamic Iceberg Flink Sink is configured using the
Builder pattern. Here are
| `setAll(Map<String, String> properties)` | Set multiple
properties at once
|
| `tableCreator(TableCreator creator)` | When DynamicIcebergSink creates new
Iceberg tables, allows overriding how tables are created - setting custom table
properties and location based on the table name. |
| `dropUnusedColumns(boolean enabled)` | When enabled, drops
all columns from the current table schema which are not contained in the input
schema (see the caveats above on dropping columns). |

group](https://nightlies.apache.org/flink/flink-docs-stable/docs/deployment/finegrained_resource/)
for the shuffle sink. |

group](https://nightlies.apache.org/flink/flink-docs-stable/docs/deployment/finegrained_resource/)
for the generator (and forward sink chained to it). |
Review Comment:
That is cleaner but I am still a bit hesitant. If the ssg names aren't
registered, these configs silently take no effect. When we do correctly
register the SSGs, this will split the config into two places (sounds like a
hidden footgun). I am slightly negative, but if you still think it's valuable
I'll make the change.
