Pull Request Overview
This PR implements a unified HA architecture by introducing a new GeneralHAService and enabling controller mode via configuration. Key changes include:
- Removing the generic init method from the HAService trait and providing a specialized implementation in GeneralHAService.
- Adding conditional initialization in GeneralHAService to select between AutoSwitchHAService and DefaultHAService based on the configuration.
- Updating the MessageStoreConfig to support controller mode and removing the obsolete HAServiceWrapper in the HA module.

- The init method now accepts only a LocalFileMessageStore, which limits its flexibility compared to the previous generic MessageStore bound. Consider generalizing the parameter if other MessageStore types are expected.
pub(crate) fn init(&mut self, message_store: ArcMut<LocalFileMessageStore>) -> HAResult<()> {

The error message in this start() method incorrectly references 'DefaultHAService'; consider updating it to 'AutoSwitchHAService' for clarity.
| error!("DefaultHAService start not implemented"); | |
| error!("AutoSwitchHAService start not implemented"); |

36-39: Fix the error message to match the service name.The error message incorrectly references "DefaultHAService" but this is the
AutoSwitchHAServiceimplementation.Apply this fix:
- error!("DefaultHAService start not implemented"); + error!("AutoSwitchHAService start not implemented");

810-811: LGTM! Clean configuration field addition.The new
enable_controller_modefield follows established patterns with proper serde annotation and integrates well with the unified HA architecture.
1002-1002: LGTM! Default value properly initialized.The default value of
falseforenable_controller_modeensures backward compatibility.rocketmq-store/src/ha/ha_service.rs (1)
32-32: LGTM! Trait interface simplification.Removing the generic
initmethod from the trait is appropriate as initialization logic is now handled in concrete implementations likeGeneralHAService.rocketmq-store/src/ha/default_ha_service.rs (1)
50-51: LGTM! Clean struct definition with Default derive.The
Defaultderive makes the struct easily instantiable and aligns with the new initialization pattern used inGeneralHAService.rocketmq-store/src/ha/general_ha_service.rs (3)
39-42: LGTM! Well-structured composition pattern.The struct design using optional fields for different HA services enables clean service selection based on configuration.
45-55: LGTM! Configuration-driven service initialization.The initialization logic properly selects between HA services based on the
enable_controller_modeflag, implementing the unified HA architecture as intended.
59-68: LGTM! Proper delegation with error handling.The start method correctly delegates to the initialized service and provides clear error handling when no service is available.
rocketmq-store/src/ha/auto_switch/auto_switch_ha_service.rs (1)
33-117: LGTM! Clean stub implementation for new HA service.The
AutoSwitchHAServiceprovides a good foundation for the controller mode HA service with appropriate placeholder methods.
