acks

[Fang Wong <fw...@salesforce.com>]

We are using kafka 0.8.2.1 and set acks to 2, see the following warning:

sent a produce request with request.required.acks of 2, which is now
deprecated and will be removed in next release. Valid values are -1, 0 or
1. Please consult Kafka documentation for supported and recommended
configuration. (kafka.server.KafkaApis)

Other settings such as acks=2 are also possible, and will require the given
number of acknowledgements but this is generally less useful.

acks=2 should be allowed, not sure why it gave warning, also what does
acks=-1 mean? Is it different from acks=0?

Thanks,
Fang

policy:
