None of the above. It doesn't even mean that the message was valid and will 
be processed at all. See 
 https://github.com/Graylog2/graylog2-server/issues/807 for a related issue 
on GitHub.


Cheers,

Hi pica, 

thanks for your reply. 

The question is: what does that means - "202 Accepted  for processing..."?

1) Got your message and it's stored on journal. Message will be processed 
eventually. It's safe...
2) Got your message and I'm going to store on my journal. Message will be 
lost if graylog terminates suddenly.

TCP does not offer such guarantees to a message sender.
