Line range hint 107-134: Refactor duplicated error handling logic

The error handling code for parsing socket addresses is duplicated for both born_host and store_host. Consider extracting this into a helper function.

+ fn parse_socket_addr(addr: &str, field_name: &str) -> Result<SocketAddr, RemotingCommand> {
+     match addr.parse::<SocketAddr>() {
+         Ok(value) => Ok(value),
+         Err(_) => {
+             warn!("parse {} failed: {}", field_name, addr);
+             Err(RemotingCommand::create_response_command()
+                 .set_code(ResponseCode::SystemError)
+                 .set_remark(&format!("parse {} failed", field_name)))
+         }
+     }
+ }

Then use it like:

msg.born_host = parse_socket_addr(&request_header.born_host, "born_host")?;
msg.store_host = parse_socket_addr(&request_header.store_host, "store_host")?;

Line range hint 135-147: Improve error handling for message decompression

The current implementation silently falls back to using the compressed body when decompression fails. This could lead to issues downstream. Consider either:

1. Propagating the decompression error
2. Logging more details about the failure
3. Adding metrics for failed decompressions

- if let Ok(decompressed) = de_result {
-     msg.message.body = Some(decompressed);
- } else {
-     warn!("err when uncompress constant");
-     msg.message.body = body.cloned();
- }
+ match de_result {
+     Ok(decompressed) => {
+         msg.message.body = Some(decompressed);
+     }
+     Err(e) => {
+         warn!("Failed to decompress message: {}", e);
+         return Ok(Some(
+             response
+                 .set_code(ResponseCode::SystemError)
+                 .set_remark(&format!("Failed to decompress message: {}", e)),
+         ));
+     }
+ }

Line range hint 171-190: Enhance observability for reply message processing

Consider adding more detailed logging and metrics to track:

1. Success/failure rates of reply message processing
2. Latency between request and reply
3. Number of unmatched replies

 async fn process_reply_message(reply_msg: MessageExt) {
+    let start = std::time::Instant::now();
     let correlation_id = reply_msg
         .message
         .get_property(&CheetahString::from_static_str(
             MessageConst::PROPERTY_CORRELATION_ID,
         ))
         .unwrap_or_default();
     if let Some(request_response_future) = REQUEST_FUTURE_HOLDER
         .get_request(correlation_id.as_str())
         .await
     {
         request_response_future.put_response_message(Some(Box::new(reply_msg)));
         if request_response_future.get_request_callback().is_some() {
             request_response_future.on_success();
         }
+        debug!(
+            "Successfully processed reply message for correlation_id={} in {:?}",
+            correlation_id,
+            start.elapsed()
+        );
     } else {
-        warn!(
+        error!(
             "receive reply message, but not matched any request, CorrelationId: {} , reply \
              from host: {}",
             correlation_id, reply_msg.born_host
         );
     }
 }
