Pull Request Overview

This PR implements previously missing data transfer methods in the HAConnection trait for DefaultHAConnection and removes redundant inherent getters.

  • Removed obsolete inherent getter methods for state and transfer metrics.
  • Added implementations for get_transferred_byte_in_second, get_transfer_from_where, and get_slave_ack_offset in the HAConnection trait impl.
Comments suppressed due to low confidence (3)

rocketmq-store/src/ha/default_ha_connection.rs:208

  • It looks like the trait HAConnection may also require a get_current_state method, but it's not implemented here; please add this to avoid a compile error and restore state management.
    }

rocketmq-store/src/ha/default_ha_connection.rs:210

  • [nitpick] Consider adding unit tests for get_transferred_byte_in_second, get_transfer_from_where, and get_slave_ack_offset to verify correct behavior under various load and error conditions.
    fn get_transferred_byte_in_second(&self) -> i64 {

rocketmq-store/src/ha/default_ha_connection.rs:210

  • [nitpick] These trait methods lack documentation; adding doc comments would clarify their purpose and expected return values for future maintainers.

Walkthrough

The code removes redundant inherent getter methods from the DefaultHAConnection struct and provides concrete implementations of these methods in the HAConnection trait implementation for DefaultHAConnection. The trait methods now delegate to the appropriate internal fields and services, consolidating access to state and metrics.

Objective Addressed Explanation
Implement missing methods in DefaultHAConnection for state management and data transfer (#3532)

Poem

In the warren of code, we hop and we bound,
Old getters removed, new trait methods found.
State and metrics, now neatly in place,
With traits in control, we quicken the pace.
Hare’s work is tidy, the changes are clear—
RocketMQ’s store is swift as a deer!

202-204: LGTM! Proper async implementation for state access.

The implementation correctly uses async RwLock read operation to safely access the current state. The method signature matches the trait definition.


214-220: Good defensive programming with fallback handling.

The implementation properly handles the case where write_socket_service is not available by returning -1, which aligns with the initialization value used elsewhere in the code.


222-224: LGTM! Correct atomic operation with appropriate ordering.

The implementation uses SeqCst ordering which provides the strongest consistency guarantees, appropriate for HA (High Availability) scenarios where data consistency is critical.


210-212: ```shell
#!/bin/bash

Display context around the u64 return in default_ha_client.rs

sed -n '630,700p' rocketmq-store/src/ha/default_ha_client.rs
echo "-----"
sed -n '700,760p' rocketmq-store/src/ha/default_ha_client.rs
