+# Migrating a `storm-kafka` spout to use `storm-kafka-client`
+
+This may not be an exhaustive list because the `storm-kafka` configs were
taken from Storm 0.9.6
+[SpoutConfig](https://github.com/apache/storm/blob/v0.9.6/external/storm-kafka/src/jvm/storm/kafka/SpoutConfig.java)
and
+[KafkaConfig](https://github.com/apache/storm/blob/v0.9.6/external/storm-kafka/src/jvm/storm/kafka/KafkaConfig.java).
+`storm-kafka-client` spout configurations were taken from Storm 1.0.6
+[KafkaSpoutConfig](https://github.com/apache/storm/blob/v1.0.6/external/storm-kafka-client/src/main/java/org/apache/storm/kafka/spout/KafkaSpoutConfig.java).

I think we should include the FirstPollOffset table in this file as well
