 spring.cloud.stream.kafka.binder.headerMapperBeanName::
 The bean name of a `KafkaHeaderMapper` used for mapping `spring-messaging` headers to and from Kafka headers.
 Use this, for example, if you wish to customize the trusted packages in a `DefaultKafkaHeaderMapper` that uses JSON deserialization for the headers.
+If this custom `KafkaHeaderMapper` bean is not made available to the binder using this property, then the binder will look for a header mapper bean with the name `kafkaBinderHeaderMapper` before falling back to a default header mapper.

 This provides an alternative option to the more common Kafka replay scenario for the case when the number of errors is relatively small and replaying the entire original topic may be too cumbersome.
 See <<kafka-dlq-processing>> processing for more information.
 Starting with version 2.0, messages sent to the DLQ topic are enhanced with the following headers: `x-original-topic`, `x-exception-message`, and `x-exception-stacktrace` as `byte[]`.
+By default, a failed record is sent to the same partition number in the DLQ topic as the original record.
+See <<dlq-partition-selection>> for how to change that behavior.
 **Not allowed when `destinationIsPattern` is `true`.**
 +
 Default: `false`.
+dlqPartitions::
+When `enableDlq` is true, and this property is not set, a dead letter topic with the same number of partitions as the primary topic(s) is created.
+Usually, dead-letter records are sent to the same partition in the dead-letter topic as the original record.
+This behavior can be changed; see <<dlq-partition-selection>>.
+If this property is set to `1` and there is no `DqlPartitionFunction` bean, all dead-letter records will be written to partition `0`.
+If this property is greater than `1`, you **MUST** provide a `DlqPartitionFunction` bean.
+Note that the actual partition count is affected by the binder's `minPartitionCount` property.
