+# 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).

+| **Setting:** `startOffsetTime`<br><br> **Default:**
`EarliestTime`<br>________________________________________________ <br>
**Setting:** `forceFromStart` <br><br> **Default:** `false` <br><br>
`startOffsetTime` & `forceFromStart` together determine the starting offset.
`forceFromStart` determines whether the Zookeeper offset is ignored.
`startOffsetTime` sets the timestamp that determines the beginning offset, in
case there is no offset in Zookeeper, or the Zookeeper offset is ignored |

**Default:** `UNCOMMITTED_EARLIEST` <br><br> [Refer to the helper
table](#helper-table-for-setting-firstpolloffsetstrategy) for picking
`FirstPollOffsetStrategy` based on your `startOffsetTime` & `forceFromStart`
settings | **Import package:**

--- End diff --
Have substituted `Kafka Config` with `Setting`, this is because I did not
succeed in restructuring the table as suggested in earlier comment. I have also
changed the heading from `KafkaSpoutConfig Name` to
`KafkaSpoutConfig/ConsumerConfig Name` because the column is a mix of both kind
of configs.
