 - `topic` (Deprecated in v0.124.0: use `logs::topic`, `metrics::topic`, and `traces::topic`) If specified, this is used as the default topic, but will be overridden by signal-specific configuration. See [Destination Topic](#destination-topic) below for more details.

 - `include_metadata_keys` (default = []): Specifies a list of metadata keys to propagate as Kafka message headers. If one or more keys aren't found in the metadata, they are ignored.
 - `partition_traces_by_id` (default = false): configures the exporter to include the trace ID as the message key in trace messages sent to kafka. *Please note:* this setting does not have any effect on Jaeger encoding exporters since Jaeger exporters include trace ID as the message key by default.
