apache-kafka - Debezium - MySQL 连接器 - Kinesis - 服务未启动

问题描述

我试图让 Debezium 将我的 CDC 事件发送到 Kinesis，服务似乎已启动，但出现错误，并且似乎没有向 Kinesis 发送任何内容。我在 Debezium 网站上遵循了这个设置指南：

https://debezium.io/documentation/reference/1.2/operations/debezium-server.html

这是我的配置文件：

debezium.sink.type=kinesis
debezium.sink.kinesis.region=us-east-1
debezium.source.connector.class=io.debezium.connector.mysql.MySqlConnector
debezium.source.offset.storage.file.filename=data/offsets.dat
debezium.source.offset.flush.interval.ms=0
debezium.source.database.hostname=127.0.0.1
debezium.source.database.id=12345
debezium.source.database.port=3306
debezium.source.database.user=*****
debezium.source.database.password=******
debezium.source.database.dbname=inventory
debezium.source.database.server.name=127.0.0.1
debezium.source.schema.whitelist=inventory

当我使用 运行服务器./run.sh时，服务器似乎开始启动，然后出现错误：

您可以在大约 3/4 的路上遇到两个与以下相关的错误：io.deb.rel.his.KafkaDatabaseHistory

使用 Kinesis 源，我不确定它为什么会抛出与 Kafka 相关的这些错误。有谁知道为什么会发生这种情况或解决方案？

标签： apache-kafkamysql-connectoramazon-kinesisdebezium

解决方案

您需要为debezium.source.database.history连接器指定属性。它的默认值为，因此对于非 Kafka 部署，请设置以下值之一：io.debezium.relational.history.KafkaDatabaseHistory
