property block.on.buffer.full default value
Hi Guys,
I was going over the producer kafka configuration, and the
property block.on.buffer.full in the documentation says:
"When our memory buffer is exhausted we must either stop accepting new
records (block) or throw errors. *By default this setting is true* and we
block, however in some scenarios blocking is not desirable and it is better
to immediately give an error. Setting this to false will accomplish that:
the producer will throw a BufferExhaustedException if a recrord is sent and
the buffer space is full."
So theoretically it should be true, but in that same documentation (
http://kafka.apache.org/documentation.html) the table has a column called
"default" that points out that the default value is actually false.
Which one is correct?
Thanks.

Ok, thanks tao.
btw: I think this is a small bug.

The default value is false.
