## Design & Implementation Details
-- Add two new configurations in `DeadLetterPolicy`:
+- Add `ProducerBuilderContext` and `ProducerBuilderCustomizer` interface:
+```java
+public interface ProducerBuilderContext {
+ /**
+ * Returns the default name of topic for the dead letter or retry letter
producer. This topic name is used
+ * unless the ProducerBuilderCustomizer overrides it.
+ *
+ * @return a {@code String} representing the input topic name
+ */
+ String getDefaultTopicName();

+ /**
+ * Returns the name of the input topic for which the dead letter or retry
letter producer is being configured.
+ *
+ * @return a {@code String} representing the input topic name
+ */
+ String getInputTopicName();
+
+ /**
+ * Returns the name of the subscription for which the dead letter or retry
letter producer is being configured.
+ *
+ * @return a {@code String} representing the subscription name
+ */
+ String getInputTopicSubscriptionName();
+}

+ /**
+ * Customize the given producer builder with settings specific to the
topic context provided.
+ *
+ * @param context the context containing information about the
input topic and the subscription
