Kafka client - 0.9

[Bharath Srinivasan <bh...@gmail.com>]

Hi,

I'm looking for the 0.9 client release plan.

https://cwiki.apache.org/confluence/display/KAFKA/Kafka+0.9+Consumer+Rewrite+Design

Is there a planned date for this release?

Thanks,
Bharath

In current high-level consumer, you can still manually control when you
commit offsets (see this blog for details:
http://ingest.tips/2014/10/12/kafka-high-level-consumer-frequently-missing-pieces/
)

While you can't explicitly roll-back a commit, you can simply avoid
committing when you have an exception (its a tiny bit more complex than
that - because the iterator stores a buffer and location in the buffer...
so you need to maintain your own collection of events to retry.... this is
also explained in the blog above).

Hope this helps.

Thanks Gwen.

I'm specifically looking for the consumer rewrite API (
org.apache.kafka.clients.consumer.KafkaConsumer). Based on the wiki, this
feature is available only in 0.9.

The specific use case is that, I wanted to use the high level consumer but
with the ability to rollback the offset in case of any exceptions. Based on
the documentation, it seems like the current high level consumer API does
not seem to be supporting it, atleast not in a straight forward fashion.

Appreciate any alternate solutions.

We don't normally plan dates for releases, when we are done with
features we want in the next release and happy with quality, we
release. Many Apache communities are like that.

If you need firmer roadmaps and specific release dates, there are few
vendors selling Kafka distributions and support.

Are there any specific features you are waiting for?
