Disable context keys in a Kafka source.

[nuekaze]

Hi,

I am using a Kafka source to read data from a topic. I would like to know if there is a way to disable the context fields from being added to the record. The fields offset, partition, source_type and topic. I found at the bottom of the docs page it says that: "By default, the kafka source augments events with helpful context keys.", but I found no way of turning it off. I tried to change the "_key" fields to empty strings in the config but that did not work either.

Hi @nuekaze ,

You can use the remap transform to remove fields you don't want, but setting them to empty string on the source should also work and so, if it isn't, do you mind opening a bug report?

I can confirm that setting the following seems to remove them all :

      headers_key: ""
      offset_key: ""
      partition_key: ""
      topic_key: ""
      key_field: ""
