I was hoping to get some clarification on the kafka connect configuration properties here https://docs.confluent.io/current/connect/userguide.html
We were having issues connecting to our confluent connect cluster to our kafka connect instance. We had all our settings configured correctly from what i could tell and didn’t have any luck.
After extensive googling some discovered that prefixing the configuration properties with “consumer.” seems to fix the issue. There is a mention of that prefix here https://docs.confluent.io/current/connect/userguide.html#overriding-producer-and-consumer-settings
I am having a hard time understanding wrapping my head around the prefix and how the properties are picked up by connect and used. It was my assumption that the java api client used by kafka connect will pick up the connection properties from the properties file. It might have some hard coded configuration properties that can be overridden by specifying the values in the properties file. But, this is not correct? The doc linked above mentions
All new producer configs and new consumer configs can be overridden by prefixing them with producer. or consumer.
What are the new configs? The link on that page just takes me to the list of all the configs. The doc mentions Occasionally, you may have an application that needs to adjust the default settings. One example is a standalone process that runs a log file connector that as the use case for using the prefix override, but this is connect cluster, how does that use case apply? Appreciate your time if you have read thus far
