Summary: KIP-693 Client-side Circuit Breaker for Partition Write
Errors
Key: KAFKA-12793
URL: https://issues.apache.org/jira/browse/KAFKA-12793
Project: Kafka
Issue Type: New Feature
Components: clients
Reporter: KahnCheny
When Kafka is used to build data pipeline in mission critical business
scenarios, availability and throughput are the most important operational goals
that need to be maintained in presence of transient or permanent local failure.
One typical situation that requires Ops intervention is disk failure, some
partitions have long write latency caused by extremely high disk utilization;
since all partitions share the same buffer under the current producer thread
model, the buffer will be filled up quickly and eventually the good partitions
are impacted as well. The cluster level success rate and timeout ratio will
degrade until the local infrastructure issue is resolved.
One way to mitigate this issue is to add client side mechanism to short circuit
problematic partitions during transient failure. Similar approach is applied in
other distributed systems and RPC frameworks.
