在Debezium中是否可以配置table_name => kafka主题映射?

问题描述

我已阅读 http://debezium.io/docs/connectors/mysql/，但我找不到有关是否可以配置debezium的任何信息，以便可以将2个(或更多)表中的更改写入相同的单个kafka主题?在我看来，它始终是1个表-> 1个主题.

I've read http://debezium.io/docs/connectors/mysql/ but I could not find any info about whether debezium can be configured so that changes from 2 (or more) tables could be written to the same, single kafka topic? It seems to me that it is always 1 table -> 1 topic.

推荐答案

是的，请使用单个消息根据您确定的链接进行转换.您可以使用正则表达式(regex)将表映射到所需的主题. io.debezium.transforms.ByLogicalTableRouter或org.apache.kafka.connect.transforms.RegexRouter都可以解决问题.后面有一个在此此处:

Yes, use Single Message Transforms, per the link you identified. You can use regular expressions (regex) to map the tables to the topic required. Both io.debezium.transforms.ByLogicalTableRouter or org.apache.kafka.connect.transforms.RegexRouter should do the trick. There's an example of the latter in this post here:

"transforms":"dropPrefix",  
"transforms.dropPrefix.type":"org.apache.kafka.connect.transforms.RegexRouter",  
"transforms.dropPrefix.regex":"DC1-TEST-(.*)",  
"transforms.dropPrefix.replacement":"$1"
