Hi Mickael,

Thanks for the KIP. Given how important tombstone records are it's hard to
believe that the console producer doesn't already support them!

I wanted to clarify the intended behavior and how it will play with the
parse.key and the newly-introduced (as of KIP-798 [1]) parse.headers
properties. Is the intention that the null.marker should match the entire
line read by the console producer, or that it can match individual portions
of a line that correspond to the record's key, value, header key, or header
value? I imagine so but think it may be worth calling out (and possibly
illustrating with an example or two) in the KIP.
