@clebertsuconic Thanks, now I see it!
Currently the MappedSequentialFileFactory doesn't extend the
AbstractSequentialFileFactory, hence it can't work for the MAPPED journal...
> Regarding MAPPED.. I didn't merge that one before because I thought we
were lacking tests... I had a test on my workspace for Unbuffered.. but I think
I missed it...
Yes, I don't know how the callbacks behave using unbuffered version, but if
it works for NIO for MAPPED it will work too..
> I think we should change the CLI to make timeout = 0 if sync = false (for
all the journals.. not just MAPPED). and add a text on the broker.xml saying we
recommend disabling if sync=false.
