I'm interested in both directions.

First of all the incoming direction: Assume that I have 10.000 
concurrent client connections sending data to the server. I've to make 
some plausibility checks for the data and afterwards I must store it in 
some way. MySQL and other DB's can't handle such amount of incoming data 
every second without a cluster behind the server I think. That's why I 
want to store (append) the data in separate CSV files and import it over 
the CSV engine from MySQL only when I need them.
To reduce the overhead of separate file / data handling and 
transformation I thought that it would be a good idea to take the 
already existing ByteBuffers and a separate connector (Mina), which 
forwards the data directly to some FileChannels using NIO. In this way I 
have a consistent data flow chain without separate overhead.

The outgoing direction: In the same model sometimes it can happen, that 
a client needs some data stored in a file. Here I want to specify the 
file over a filechannel and redirect the ByteBuffer data over the chain 
directly to the clients (eventually using some of the filters to modify 
parts of the content).

What do you think?
