+                <para><emphasis role="strong">SendRecvBatch.java</emphasis> uses explicit batch operations.
+                  You manually create message batches and call <code>sendMessageBatch()</code> and
+                  <code>deleteMessageBatch()</code> directly. You also handle batch responses, including any
+                  failed messages. This approach gives you full control over batch sizing and error handling.
+                  However, it requires more code to manage the batching logic.</para>
+                <para><emphasis role="strong">SimpleProducerConsumer.java</emphasis> uses the high-level
+                  <code>SqsAsyncBatchManager</code> library for automatic request batching. You make
+                  individual <code>sendMessage()</code> and <code>deleteMessage()</code> calls with the same
+                  method signatures as the standard client. The SDK automatically buffers these calls and
+                  sends them as batch operations. This approach requires minimal code changes while providing
+                  batching performance benefits.</para>
+                <para>Use explicit batching when you need fine-grained control over batch composition and
+                  error handling. Use automatic batching when you want to optimize performance with minimal
