StreamFromKafkaSpec:

Reading messages from Kafka
- should be written to Iceberg
  + Given an Iceberg created with:

CREATE TABLE polaris.my_namespace.StreamFromKafkaSpec (
  id int,
  label String,
  partitionKey long,
  date Date,
  timestamp Timestamp
) USING iceberg TBLPROPERTIES (
  'format-version' = '2',
  'sort-order' = 'partitionKey ASC NULLS FIRST',
  'write.distribution-mode' = 'none'
) PARTITIONED BY (partitionKey); 
  + And a Kafka topic called polaris.my_namespace.StreamFromKafkaSpec1747154279615 
  + When we send 1024 records to Kafka 
  + And read from the Kafka topic writing to the Iceberg table 
  + Then the table is populated with data 
  + And the number of data files (8) is the same as the number of Spark partitions, not the number of Kafka partitions (24)
