我注意到我的Kafka Streams应用程序在一段时间内无法与Kafka通信后将进入ERROR状态。我想找到一种使Kafka Streams本质上“永远重试”而不是进入ERROR状态的方法。唯一的解决方法是重新启动我的Kafka Streams应用程序，这不理想。
我在Kafka Streams配置中设置了request.timeout.ms=2147483647。我注意到这有帮助（它过去大约一分钟进入ERROR状态，现在它的发生频率降低了，但最终还是会发生）。
这是我的Kafka Streams配置：
commit.interval.ms: 10000
cache.max.bytes.buffering: 0
retries: 2147483647
request.timeout.ms: 2147483647
retry.backoff.ms: 5000
num.stream.threads: 1
state.dir: /tmp/kafka-streams
producer.batch.size: 102400
producer.max.request.size: 31457280
producer.buffer.memory: 314572800
producer.max.in.flight.requests.per.connection: 10
producer.linger.ms: 0
consumer.max.partition.fetch.bytes: 31457280
consumer.receive.buffer.bytes: 655360
这是来自Kafka Streams的日志的相关部分：
