我有一个Kafka Connect S3 Sink，将记录写到Amazon S3。此特定接收器的写入速度约为4k rec / sec。每隔几天，Kafka Connect工作程序任务之一就会失败，并显示以下错误。手动重启完全可以解决该问题，直到几天后再次发生。
我还将“ s3.part.retries”从默认值“ 3”增加到“ 10”，但这似乎没有效果。
还有其他解决方案吗？
我正在使用Kafka 2.0.1运行Confluent 5.0.1。我看不到最新和最出色的Confluent 5.1.2（https://docs.confluent.io/current/connect/kafka-connect-s3/changelog.html）
