63-65: Consider the performance implications of owned stringsThe change from
&strtoStringfor both key and value parameters forces memory allocation for each property insertion. While this provides cleaner ownership semantics, it might impact performance in high-throughput scenarios where properties are frequently set.Consider whether a more flexible API could be provided:
- Accept
Into<String>to allow both owned and borrowed strings- Provide both variants (borrowed and owned) to let users choose based on their use case
fn put_property<K, V>(&mut self, key: K, value: V) where K: Into<String>, V: Into<String>
111-113: Consider transaction ID string lifecycleThe change to owned
Stringfor transaction IDs is consistent with other changes. However, transaction IDs are typically generated and used temporarily.Consider implementing a builder pattern for message construction to make the ownership requirements more explicit:
impl MessageClientExt { pub fn with_transaction_id(mut self, transaction_id: impl Into<String>) -> Self { self.set_transaction_id(transaction_id.into()); self } }
Line range hint
63-113: Document migration impact for API consumersThese signature changes (
&str→String) across multiple methods constitute a breaking change that will affect all consumers of theMessageTraitAPI.Recommendations:
- Document the changes in CHANGELOG.md
- Consider providing a migration guide
- Update the crate version according to semver (this requires a major version bump)
- Consider adding deprecation notices in the previous version if possible
rocketmq-broker/src/transaction/queue/transactional_message_util.rs (1)
86-87: Consider optimizing constant string allocationsWhile the current implementation correctly handles string ownership, consider optimizing the constant string allocations. Since
PROPERTY_TRANSACTION_PREPAREDand"true"are constant values, we could potentially avoid repeated allocations.Consider using a static string or lazy initialization for these constant values:
lazy_static! { static ref PREPARED_TRUE: String = "true".to_owned(); } // Then in the code: MessageAccessor::put_property( &mut msg_inner, MessageConst::PROPERTY_TRANSACTION_PREPARED.to_owned(), PREPARED_TRUE.clone(), );This would reduce allocations when this method is called frequently.
rocketmq-common/src/common/message/message_client_id_setter.rs (1)
125-126: Consider optimizing the constant property key.Since
PROPERTY_UNIQ_CLIENT_MESSAGE_ID_KEYIDXis a constant value, consider avoiding repeated allocations by using a static string or string interning pattern.Here's a potential optimization:
lazy_static! { static ref UNIQ_CLIENT_MESSAGE_ID_KEY: String = MessageConst::PROPERTY_UNIQ_CLIENT_MESSAGE_ID_KEYIDX.to_owned(); } // Then in set_uniq_id: message.put_property(UNIQ_CLIENT_MESSAGE_ID_KEY.clone(), uniq_id);rocketmq-client/src/utils/message_util.rs (1)
101-101: LGTM! Consider using into_iter for efficiency.The ownership handling is correct. For a minor optimization, consider using
into_iter()since we're taking ownership of all values:- for (key, value) in properties { + for (key, value) in properties.into_iter() {rocketmq-common/src/common/message/message_ext_broker_inner.rs (3)
187-189: LGTM! The ownership model change improves clarity.Taking ownership of both key and value strings upfront is more efficient than borrowing, as these properties need to be stored in the message. This change eliminates potential hidden clones and makes the ownership requirements explicit at the API level.
Consider documenting this ownership pattern in the module-level documentation to ensure consistent usage across the codebase.
235-237: LGTM! Ownership model suits transaction ID semantics.Taking ownership of the transaction ID is appropriate as it's a persistent identifier that must live with the message throughout its lifecycle.
This change completes a consistent pattern across the message trait implementation where all persistent identifiers (topic, transaction ID) and properties take ownership of their string values. This approach:
- Makes the API more predictable
- Prevents hidden allocations
- Clearly communicates ownership requirements
Line range hint
187-237: The MessageTrait signature optimizations follow solid API design principles.The changes to
put_property,set_topic, andset_transaction_idrepresent a cohesive optimization that improves the API design by:
- Making ownership requirements explicit at the API level
- Eliminating potential hidden allocations
- Following consistent patterns across related methods
- Aligning with Rust's ownership model best practices
The implementation maintains proper delegation to the inner message while providing a cleaner external interface.
Consider adding the following to strengthen this change:
- Document this ownership pattern in the trait-level documentation
- Add examples showing proper string ownership handling for common use cases
- Consider creating a style guide entry for similar string ownership patterns in message handling
rocketmq-common/src/common/message/message_accessor.rs (2)
45-45: Consider performance implications of owned String parameters.While changing from
&strtoStringprovides cleaner ownership semantics, it forces callers to clone strings even when a reference would suffice. This could impact performance in high-throughput scenarios.Consider using
Into<String>to provide flexibility:-pub fn put_property<T: MessageTrait>(msg: &mut T, name: String, value: String) +pub fn put_property<T: MessageTrait, S1: Into<String>, S2: Into<String>>( + msg: &mut T, + name: S1, + value: S2, +)This allows both
Stringand&strwhile maintaining ownership semantics.
67-68: Consistent pattern of property name cloning.The pattern of cloning constant property names with
to_owned()is consistent but potentially inefficient. These constants are static and could be handled more efficiently.Consider using
Cow<'static, str>for the constants inMessageConstto avoid unnecessary cloning:pub const PROPERTY_TRANSFER_FLAG: Cow<'static, str> = Cow::Borrowed("TRANSFER_FLAG");Also applies to: 92-93
rocketmq-common/src/common/message/message_ext.rs (2)
294-296: Consider optimization for frequently reused topics.Taking ownership of the topic string is consistent with the ownership model, but consider providing an additional method that accepts
&strfor cases where the same topic is reused across multiple messages to avoid unnecessary allocations.+ fn set_topic_ref(&mut self, topic: &str) { + self.message.set_topic(topic.to_string()); + }
Line range hint
278-328: Consider documenting the ownership model change.The consistent shift to taking ownership of strings across all methods improves API predictability but represents a breaking change. Consider:
- Adding documentation explaining the ownership model
- Providing migration guidance for existing callers
- Including performance considerations in the documentation
rocketmq-client/src/implementation/client_remoting_processor.rs (1)
160-161: Consider using static strings for constant properties.The
to_owned()call onPROPERTY_REPLY_MESSAGE_ARRIVE_TIMEcreates a new allocation for each message.

296-297: Consider reducing duplication of property key conversion.While the ownership changes are correct, the same property key is converted twice. Consider storing the converted key in a variable to avoid redundant
to_owned()calls.pub fn renew_immunity_half_message_inner(msg_ext: &MessageExt) -> MessageExtBrokerInner { let mut message_inner = Self::renew_half_message_inner(msg_ext); + let prepared_queue_offset_key = MessageConst::PROPERTY_TRANSACTION_PREPARED_QUEUE_OFFSET.to_owned(); let queue_offset_from_prepare = msg_ext.get_user_property(MessageConst::PROPERTY_TRANSACTION_PREPARED_QUEUE_OFFSET); if let Some(queue_offset_from_prepare) = queue_offset_from_prepare { MessageAccessor::put_property( &mut message_inner, - MessageConst::PROPERTY_TRANSACTION_PREPARED_QUEUE_OFFSET.to_owned(), + prepared_queue_offset_key.clone(), queue_offset_from_prepare, ); } else { MessageAccessor::put_property( &mut message_inner, - MessageConst::PROPERTY_TRANSACTION_PREPARED_QUEUE_OFFSET.to_owned(), + prepared_queue_offset_key, msg_ext.queue_offset.to_string(), ); }Also applies to: 302-303

321-321: LGTM! Improved string handling efficiency.The change simplifies the topic assignment by removing unnecessary string conversion, aligning with the broader initiative to optimize method signatures and string ownership handling across the codebase.
Consider adding a comment explaining the namespace handling for better maintainability, as this is a critical part of the message routing logic:
+ // Ensure topic includes the namespace prefix for proper message routing msg.set_topic(self.default_producer.with_namespace(msg.get_topic()));rocketmq-client/src/consumer/consumer_impl/pull_api_wrapper.rs (1)
182-183: LGTM: Improved property handling with proper string ownership.The changes correctly ensure ownership of property keys and values. Consider extracting these constant string conversions to a static or const if these properties are used frequently across the codebase.
// Consider adding these constants at the module level: const PROPERTY_MIN_OFFSET_OWNED: String = MessageConst::PROPERTY_MIN_OFFSET.to_owned(); const PROPERTY_MAX_OFFSET_OWNED: String = MessageConst::PROPERTY_MAX_OFFSET.to_owned();Also applies to: 187-188

215-392: Consider documenting string ownership strategy.Given the focus on optimizing string handling across MessageTrait, it would be valuable to document the string ownership strategy (when to use String vs &str) in the module documentation. This would help maintain consistency as the codebase evolves.
rocketmq-common/src/common/message/message_decoder.rs (1)
465-465: LGTM! Improved string ownership handling.The change from
get_topic()toget_topic().to_owned()properly converts the borrowed topic string into an owned String. This prevents potential lifetime issues and aligns with Rust's ownership model, though it introduces a minor memory allocation overhead from cloning.Consider adding a comment explaining the ownership transfer requirement if this pattern needs to be followed consistently across the codebase:
- message_client_ext.set_topic(message_ext.get_topic().to_owned()); + // Convert borrowed topic to owned String to prevent lifetime issues + message_client_ext.set_topic(message_ext.get_topic().to_owned());rocketmq-broker/src/processor/reply_message_processor.rs (1)

51-52: Consider performance implications of owned String parameters.While the change to owned
Stringparameters makes ownership semantics clearer and reduces lifetime annotations, it forces allocations at call sites even for temporary strings. Consider usingInto<String>for more flexibility:-fn set_topic(&mut self, topic: String); +fn set_topic(&mut self, topic: impl Into<String>);This would allow both

249-259: Consider caching cloned strings to optimize performance.While the changes to use owned strings are correct, multiple
to_owned()calls on the same values could impact performance. Consider caching the cloned strings when they're used multiple times.pub async fn send_message_back(&mut self, msg: &MessageExt) -> bool { + let topic = msg.get_topic().to_owned(); // ... other code ... MessageAccessor::put_property( &mut new_msg, MessageConst::PROPERTY_RETRY_TOPIC.to_owned(), - msg.get_topic().to_owned(), + topic, );rocketmq-client/src/producer/default_mq_producer.rs (1)
686-686: LGTM! Consistent optimization across all message sending methods.The changes systematically remove
.as_str()calls when setting message topics across all sending patterns:
- Basic send methods
- Queue-specific send methods
- Selector-based send methods
- Request methods
This optimization aligns with the PR objective of improving MessageTrait's method signatures.
The consistent application of this change across all methods improves code maintainability by:
- Reducing unnecessary string conversions
- Providing a more ergonomic API that works directly with owned String values
- Maintaining uniform behavior across all message sending patterns

79-81: Verify topic string ownership requirements
The change to accept owned String for topics aligns with the broader API changes. However, topics are often static or long-lived strings in message systems.
Let's verify how topics are typically used in the codebase:
✅ Verification successful
Based on the search results, I can now generate the final response since I have enough information about how topics are used in the codebase:
Topic ownership change is appropriate and consistent with codebase patterns
The change to accept owned String for topics is well-aligned with the codebase's patterns:
- Topics are consistently stored as owned
Stringin message queues, configs, and other structures - The codebase frequently performs topic name manipulations (namespace wrapping, retry topic conversion, etc.) which benefit from owned strings
- No static/const topic definitions were found that would suggest topics are primarily static

58-58: LGTM: Simplified string handling
The change to unwrap_or_default() is more idiomatic and eliminates unnecessary string operations while maintaining safe fallback behavior.
80-80: LGTM: Consistent string handling improvement
The change maintains consistency with the previous string handling optimization while ensuring safe default behavior.

125-126: LGTM! Change aligns with signature optimization objectives.
The modification to use to_owned() for the property key aligns with the PR's objective of optimizing method signatures and follows consistent string ownership patterns across the codebase.
rocketmq-client/src/utils/message_util.rs (3)
48-49: LGTM! Ownership handling is correct.
The implementation correctly handles ownership:
- The key is converted to owned string
- The value is already owned from get_property()
57-58: LGTM! Consistent property handling pattern.
The implementation maintains consistency with the previous property setting pattern, correctly handling ownership for both keys and values.
Also applies to: 64-65
Line range hint 37-101: Verify consistent property handling across the codebase.
Let's ensure these ownership changes are consistently applied across all message property handling code.
✅ Verification successful
Based on the search results, I can now generate the final response since I have comprehensive information about message property handling and topic setting across the codebase:
Property handling and topic setting are consistently implemented across the codebase
The code review concern about ownership changes is unfounded as the codebase shows:
-
All
MessageAccessor::put_propertycalls consistently use.to_owned()for both key and value parameters across all usages in:- Message utilities (
message_util.rs) - Producer implementations (
default_mq_producer_impl.rs) - Consumer implementations (
default_mq_push_consumer_impl.rs) - Transaction handling (
transactional_message_bridge.rs)
- Message utilities (
-
Topic setting via
set_topicis also consistently implemented with ownedStringtypes across all message-related structs:- Base message traits (
common/message.rs) - Message implementations (
message_single.rs,message_batch.rs) - Message extensions (
message_ext.rs,message_client_ext.rs)
- Base message traits (
The property handling in the reviewed code follows the established patterns throughout the codebase.

137-138: LGTM! Efficient string ownership handling.
The change from &str to String parameters is a good optimization as it eliminates unnecessary string cloning, since the HashMap needs to own the strings anyway.
153-154: LGTM! Appropriate ownership transfer for topic.
The change to accept String directly is appropriate since the topic needs to be owned by the message.

The change to accept owned String for topics is appropriate since topics are fundamental message identifiers that need to be stored for the message's lifetime.
Let's verify the impact on callers:
✅ Verification successful
LGTM! The change to owned String is consistent with the codebase patterns
The codebase search reveals that all set_topic implementations consistently accept owned String, and callers are properly handling ownership:
- Message types like
MessageQueue,MessageClientExt,MessageSingle, etc. all use ownedString - Callers properly handle ownership by:
- Using
to_owned()when needed (e.g. inmessage_decoder.rs) - Passing owned strings from methods like
with_namespace() - Cloning when required (e.g. in
default_pull_message_result_handler.rs)
- Using

The MQ2 flag handling is consistent with other property management methods.
170-174: 🛠️ Refactor suggestion
Consider adding validation for numeric properties.
The reconsume times properties likely represent numeric values but are handled as strings without validation.
Let's check if these properties are used as numbers elsewhere:
Consider adding type safety:
pub fn set_reconsume_time<T: MessageTrait>(msg: &mut T, reconsume_times: u32) {
msg.put_property(
MessageConst::PROPERTY_RECONSUME_TIME.to_owned(),
reconsume_times.to_string(),

326-328: LGTM! Ownership model suits transaction IDs.
Taking ownership of the transaction ID is appropriate since these IDs are typically unique per message and not reused, making the ownership transfer efficient.
278-280: Verify impact of ownership change on callers.
The change from &str to String parameters provides cleaner ownership semantics but may require additional allocations at call sites. This could impact performance if the method is called frequently with string literals or borrowed strings.
✅ Verification successful
Change to String parameters is consistent with existing usage patterns
Based on the search results, the change from &str to String parameters aligns well with the codebase's patterns:
-
All callers already use
.to_owned()or.to_string()when callingput_property:- Message constants are converted:
MessageConst::PROPERTY_KEYS.to_owned() - String values are converted:
level.to_string() - No direct string literals are passed
- Message constants are converted:
-
The implementation in
Message(base type) stores owned strings in a HashMap:fn put_property(&mut self, key: String, value: String) { self.properties.insert(key, value); }
-
The pattern is consistently used across all message types (MessageExt, MessageBatch, MessageClientExt, etc.) and throughout the codebase's message processing chain.
The change provides cleaner ownership semantics without introducing additional allocations since callers were already creating owned strings.

257-258: LGTM! Ownership semantics improvement
The change from &str to String parameters improves ownership semantics and eliminates potential lifetime management complexity. While this may introduce a small allocation cost for string literals, it's a worthwhile tradeoff for clearer APIs and reduced complexity in the calling code.
273-274: LGTM! Consistent with field type
Taking ownership of the topic string is consistent with the field's type and eliminates unnecessary conversions. This change provides a more intuitive API that clearly communicates ownership transfer.
Line range hint 257-310: Verify impact on other MessageTrait implementors
The signature changes to MessageTrait methods may require updates in other implementations of this trait.
✅ Verification successful
All MessageTrait implementations are consistent with the changes
Based on the search results, I found all implementations of MessageTrait and verified that they have consistent method signatures for put_property, set_topic, and set_transaction_id:
- MessageSingle (Message)
- MessageExt
- MessageClientExt
- MessageExtBrokerInner
- MessageBatch
All implementations follow the same signature pattern and handle the methods appropriately, delegating to inner implementations where necessary. The changes are properly reflected across the codebase.

Line range hint 214-227: Consider handling potential integer overflow
The calculation of acc_total subtracts queue_offset from max_offset. While this is generally safe, there could be edge cases where this subtraction might overflow if max_offset is significantly smaller than queue_offset.
Let's verify the possible range of these values:
Consider using checked subtraction to handle potential overflow cases:

let message_ext = messages.last().unwrap();
if let Some(property) = message_ext.get_property(MessageConst::PROPERTY_MAX_OFFSET) {

The send_message_in_transaction method assumes a transaction listener is properly configured. Let's verify this assumption to prevent potential runtime issues.
✅ Verification successful
Let me verify the transaction listener configuration by checking the implementation details in the producer.
Transaction listener validation is properly implemented
The implementation includes proper safeguards for transaction listener:
- Transaction listener is stored as an
Option<Arc<Box<dyn TransactionListener>>>field - The
set_transaction_listenermethod safely wraps and stores the listener - The transaction listener is checked and used during message processing via
unwrap()

Since this change is part of optimizing MessageTrait's method signatures, let's verify that similar string ownership improvements are consistently applied across the codebase.
✅ Verification successful
String ownership handling is consistently implemented across MessageTrait implementations
Based on the analysis of the codebase:
-
All MessageTrait implementations (Message, MessageExt, MessageClientExt, MessageExtBrokerInner, MessageBatch) consistently handle string ownership:
get_topic()returns&strreferencesset_topic()takes ownedStringvalues- The reviewed code follows this pattern by using
to_owned()when transferring ownership
-
The string ownership pattern is consistently applied across the codebase, with callers properly handling ownership:
- When setting topics, owned Strings are passed
- When reading topics, references are used unless ownership transfer is needed
to_owned(),to_string(), andclone()are used appropriately when ownership is required

Optimization of set_topic calls is correct and verified
The search results confirm that MessageTrait (defined in rocketmq-common/src/common/message.rs) declares set_topic to accept String parameter: fn set_topic(&mut self, topic: String);. This signature is consistently implemented across all message types including MessageSingle, MessageBatch, and MessageExt.

Maintain consistent ownership handling for topic and properties.
There's an inconsistency in ownership handling. While properties are converted to owned strings using to_owned(), the topic is set directly without ownership conversion. This should be consistent with the property handling pattern.

💡 Codebase verification
Based on the comprehensive search results, I can now generate the final response:
Update transaction_id handling in MessageBatch implementation
The current implementation of get_transaction_id() in MessageBatch is unsafe as it assumes transaction_id is always Some() by using unwrap(). The code search reveals that:
- The
transaction_idfield is consistently defined asOption<String>across the codebase - There are multiple places where
transaction_idis explicitly set toNone - Other implementations like
MessageSingle::transaction_id()properly returnOption<&str>
The trait should be updated to handle optional transaction IDs:
- fn get_transaction_id(&self) -> &str {
- self.final_message.transaction_id.as_deref().unwrap()
- }
+ fn get_transaction_id(&self) -> Option<&str> {
+ self.final_message.transaction_id.as_deref()
+ }This change requires updating the Message trait and all its implementations to handle optional transaction IDs consistently.
🔗 Analysis chain
Verify transaction_id handling.
While the setter implementation is correct, there's a potential issue with the corresponding getter method. The get_transaction_id() method assumes the transaction_id is always Some() by using unwrap(), which could panic if transaction_id is None.
Consider updating the getter to handle the None case:
- fn get_transaction_id(&self) -> &str {
- self.final_message.transaction_id.as_deref().unwrap()
- }
+ fn get_transaction_id(&self) -> Option<&str> {
+ self.final_message.transaction_id.as_deref()
+ }Let's verify if transaction_id can be None in practice:
Let me gather more information to verify the transaction_id handling comprehensively.

🛠️ Refactor suggestion
Consider using a timestamp-specific type.
The timestamp property would be better served by a proper timestamp type rather than a raw string.
Consider using std::time::SystemTime or chrono::DateTime:
pub fn set_consume_start_time_stamp<T: MessageTrait>(
msg: &mut T,
timestamp: SystemTime,
) {
msg.put_property(
MessageConst::PROPERTY_CONSUME_START_TIMESTAMP.to_owned(),
timestamp.duration_since(UNIX_EPOCH)
.unwrap()
.as_millis()
.to_string(),

Fix inconsistency between getter and setter
There's a potential runtime panic in the current implementation:
set_transaction_idstores the ID asOption<String>get_transaction_idassumes it's alwaysSomeand unwraps unconditionally
Consider one of these approaches:
- fn get_transaction_id(&self) -> &str {
- self.transaction_id.as_deref().unwrap()
- }
+ // Option 1: Return Option to match the storage type
+ fn get_transaction_id(&self) -> Option<&str> {
+ self.transaction_id.as_deref()
+ }
+ // Option 2: Document and enforce invariant
+ fn get_transaction_id(&self) -> &str {
+ self.transaction_id.as_deref()
+ .expect("Transaction ID must be set before calling get_transaction_id")
+ }The first option is safer as it properly exposes the optional nature of the transaction ID through the type system.

Improve error handling in put_user_property.
While the validation logic is sound, using panic! for input validation isn't idiomatic Rust. Consider returning a Result instead:
