Offset after message deletion

[Imre Nagi <im...@gmail.com>]

Hi All,

I'm new in kafka. So, I have a question related to kafka offset.

<http://kafka.apache.org/documentation.html>, it said :

After the message has been discarded, let say that we receive some new
message. What is the offset of the new message? Will it restart from 0 or
continue the latest offset?

Thanks,
Imre

It will continue from the latest offset. offset is a increasing, contiguous
sequence number per partition.
