Pull Request Overview
This PR implements additional components for high-availability support by introducing dedicated services for connection state notifications and group transfers along with refining the HA service initialization. Key changes include:
- Introduction of HAConnectionStateNotificationService and GroupTransferService as new service module files.
- Refactoring of DefaultHAService in its instantiation and initialization flow.
- Updates to the GeneralHAClient and module registration to support new HA services.

- The initialization logic has shifted from using DefaultHAService::default() and init(message_store) to DefaultHAService::new(message_store) followed by init(). Please update the inline documentation to clarify this refactoring and ensure consistency with the new API design.
let mut default_ha_service = DefaultHAService::new(message_store);

- [nitpick] The field 'accept_socket_service' is declared without any accompanying documentation or implementation details. Consider adding a comment or a TODO to explain its purpose and future implementation.

🧹 Nitpick comments (5)
rocketmq-store/src/ha/group_transfer_service.rs (1)
18-18: Incomplete implementation - consider adding documentation or TODO comments.The
GroupTransferServicestruct is currently empty with no fields or methods. While placeholder implementations are acceptable during initial development, consider adding:
- Documentation describing the intended purpose and functionality
- TODO comments outlining planned features
- Basic field structure if the design is already known
Would you like me to help draft documentation or suggest a basic structure based on common HA group transfer patterns?
rocketmq-store/src/ha/ha_connection_state_notification_service.rs (1)
18-18: Incomplete implementation - add documentation for clarity.Similar to
GroupTransferService, this struct is empty and provides no functionality. The name suggests it should handle HA connection state notifications, but without documentation or structure, its intended purpose is unclear.Consider adding:
- Documentation explaining the service's role in the HA infrastructure
- Basic field structure or method signatures if the design is established
- TODO comments for planned functionality
rocketmq-store/src/ha/general_ha_client.rs (2)
21-24: Consider naming consistency and add getter methods.The struct field names don't align with the setter method names:
- Field:
default_ha_servicevs Method:set_default_ha_service- Field:
auto_switch_ha_servicevs Method:set_auto_switch_ha_serviceConsider adding corresponding getter methods for accessing the services:
+ pub fn get_default_ha_service(&self) -> Option<&DefaultHAClient> { + self.default_ha_service.as_ref() + } + + pub fn get_auto_switch_ha_service(&self) -> Option<&AutoSwitchHAClient> { + self.auto_switch_ha_service.as_ref() + }Also applies to: 40-46
48-48: Improve comment specificity.The comment is too generic. Consider being more specific about what additional methods might be needed.
- // Additional methods to interact with the HA services can be added here + // TODO: Add methods for service lifecycle management, status checking, and delegation to active servicerocketmq-store/src/ha/default_ha_service.rs (1)
184-184: Consider implementing or documenting AcceptSocketService.The
AcceptSocketServiceis currently an empty struct, which appears to be a placeholder. Consider either implementing its functionality or adding documentation explaining its future purpose.If this is intentional as a placeholder, consider adding a comment:
+// TODO: Implement AcceptSocketService functionality struct AcceptSocketService;

rocketmq-store/src/ha.rs (1)
26-26: LGTM! Consistent module organization.The new private module declarations properly integrate the new HA service components into the module hierarchy. The visibility is appropriately restricted since these are internal service components.
Also applies to: 31-31
rocketmq-store/src/ha/general_ha_service.rs (1)
52-53: Improved initialization pattern - verify consistency across codebase.The change from
DefaultHAService::default()+init(message_store)toDefaultHAService::new(message_store)+init()is an architectural improvement that makes dependencies explicit at construction time.However, ensure this change is consistently applied throughout the codebase:
#!/bin/bash # Description: Verify all DefaultHAService usage follows the new initialization pattern # Expected: All instances should use new() constructor, no default() calls remaining echo "Searching for DefaultHAService usage patterns..." rg -A 3 "DefaultHAService::" --type rust echo -e "\nChecking for any remaining default() usage..." rg "DefaultHAService::default" --type rustrocketmq-store/src/ha/general_ha_client.rs (2)
26-30: LGTM! Proper Default trait implementation.The Default trait correctly delegates to the
new()constructor, maintaining consistency.
32-38: Clean constructor implementation.The constructor properly initializes both optional service fields to
None, providing a clean starting state.rocketmq-store/src/ha/default_ha_service.rs (5)
36-36: New atomic type import looks appropriate.The
AtomicU64import is needed for the new counter fields in the struct.
43-45: Service imports align with PR objectives.The imports for
GeneralHAClient,GeneralHAConnection,GroupTransferService, andHAConnectionStateNotificationServiceproperly support the comprehensive HA infrastructure implementation described in the PR objectives.Also applies to: 49-49
69-81: Constructor implementation is well-structured.The constructor properly initializes all fields with appropriate default values and takes the necessary
message_storeparameter. The initialization pattern is consistent and follows Rust best practices.
94-94: Init method signature change is logical.Removing the
message_storeparameter frominit()makes sense since the struct now holds the message store as a field initialized during construction.
56-66: Review atomic type consistency with trait methods.The struct uses
AtomicU64for counters, but some trait methods expect different atomic types. For example,get_connection_count()returns&AtomicI32while you're usingAtomicU64forconnection_count.#!/bin/bash # Check what atomic types the HAService trait methods expect ast-grep --pattern 'fn get_connection_count($$$) -> &AtomicI32' ast-grep --pattern 'fn get_push_to_slave_max_offset($$$) -> &AtomicI64'
