 ## Batching
 
-If batching is enabled, then the producer accumulates and sends a batch of messages in a single request. Batching size is defined by the maximum number of messages and maximum publish latency.

+
+## Chunking
+
+Message chunking enables Macrometa to process large payload messages by splitting the message into chunks at the producer side and aggregating chunked messages at the consumer side.
+
+With message chunking enabled, when the size of a message exceeds the allowed maximum payload size (5MB), the producer splits the original message into chunked messages and publishes them. The consumers automatically consume the aggregated message.
+
+:::note
+
+- Chunking is only available for persistent topics.
+- Chunking cannot be enabled simultaneously with batching. Before enabling chunking, you must turn off batching.
+
+:::
+
+
+### Enable Message Chunking
+
+**Prerequisite**: Turn off batching by setting the `batching_enabled` parameter to `false`.
+
+The message chunking feature is off by default. To enable message chunking, set the `chunkingEnabled` parameter to true when creating a producer.
+
+:::note
+If the consumer fails to receive all chunks of a message within a specified period, then it expires incomplete chunks. The default value is 1 minute.
