Enum OnKeyError 

pub enum OnKeyError {
    Skip,
    Fail,
    RoundRobin,
}

What the sink does when key/partition extraction fails for a record.

Variants

Skip

Drop the record (logs a warning).

Fail

Surface FaucetError::Sink and abort the batch.

RoundRobin

Send the record with no key (librdkafka picks the partition).
