Consumer group protocol mismatch between static membership and dynamic assignment triggers rebalance loop.

generic

消费者组的静态成员和动态分配协议不匹配，导致重平衡循环。

80% success Set 'partition.assignment.strategy' to 'org.apache.kafka.clients.consumer.RangeAssignor' and ensure all consumers use the same protocol version.
```
Set 'partition.assignment.strategy' to 'org.apache.kafka.clients.consumer.RangeAssignor' and ensure all consumers use the same protocol version.
```
85% success Disable static group membership by removing group.instance.id from consumer config and rebalance with 'KafkaConsumer#enforceRebalance'.
```
Disable static group membership by removing group.instance.id from consumer config and rebalance with 'KafkaConsumer#enforceRebalance'.
```
90% success Upgrade broker to 3.7+ and enable cooperative rebalance protocol with 'CooperativeStickyAssignor'.
```
Upgrade broker to 3.7+ and enable cooperative rebalance protocol with 'CooperativeStickyAssignor'.
```

设置 'partition.assignment.strategy' 为 'org.apache.kafka.clients.consumer.RangeAssignor'，并确保所有消费者使用相同的协议版本。

从消费者配置中移除 group.instance.id 以禁用静态成员，并使用 'KafkaConsumer#enforceRebalance' 触发重平衡。

升级代理到 3.7+ 并使用 'CooperativeStickyAssignor' 启用协作式重平衡协议。

Common approaches that don't work:

90% fail
Restarting does not resolve protocol mismatch; rebalance triggers again on rejoin.
70% fail
Longer timeout delays detection but does not fix assignment logic.
60% fail
Removing static membership may cause duplicate assignments and offset commits.
