Stefan Miklosovic commented on CASSANDRA-21372:
-----------------------------------------------
[~dnk] couldnt we also provide {{-XX:AsyncLogBufferSize}} with e.g. default
value (I think it is 2MB). We can comment it out. I would just put it there too
so people can enable it easily if they need something bigger. As I understand
it, if the log messages wont fit into the buffer, they will be just discarded.
If somebody wants async logging but still wants to be safe(r) in this aspect
they can tweak it easily.
