Ismael Juma updated KAFKA-4935:
-------------------------------
Summary: Consider disabling record level CRC checks for message format V2
(was: Disable record level crc checks on the consumer with the KIP-98 message
format)
> Consider disabling record level CRC checks for message format V2
> ----------------------------------------------------------------
>
> Key: KAFKA-4935
> URL: https://issues.apache.org/jira/browse/KAFKA-4935
> Project: Kafka
> Issue Type: Improvement
> Reporter: Apurva Mehta
> Fix For: 0.11.0.0
>
>
> With the new message format proposed in KIP-98, the record level CRC has been
> moved to the the batch header. The consumer record API still allows retrieval
> of CRC per record, and in this case we compute the CRC on the fly. This
> degrades performance, and also such a computation becomes unnecessary with
> the batch level CRC.
> We can address this by deprecating the record level CRC api. We can also work
> around this by disabling record level checks when the check crc config is set
> to false.
