> With the new message format proposed in KIP-98, the record level CRC has been
> moved to the the batch header.
> Because we expose the record-level CRC in `RecordMetadata` and
> `ConsumerRecord`, we currently compute it eagerly based on the key, value and
> timestamp even though these methods are rarely used. Ideally, we'd deprecate
> the relevant methods in `RecordMetadata` and `ConsumerRecord` while making
> the CRC computation lazy. This seems pretty hard to achieve in the Producer
> without increasing memory retention, but it may be possible to do in the
> Consumer.
> An alternative option is to return the batch CRC from the relevant methods.
