Review Comment: P.S. Can we add a flag to this example that, when enabled, will run the pipeline in `IcebergRestCatalogStreamingWriteExample` beforehand? i.e. so users can run this as a standalone example instead of asking them to run two separate examples. -- This is an automated message from the Apache Git Service.
