[infinispan-dev] ISPN-78 and Large Object Support/Streaming API

[Philippe Van Dyck]

It may sound a bit extreme but what about using streams as the base
interface and converting values to streams asap ?

The conversion could be seen as the marshaling operation and the result as a
stream of bytes ?

The 'base' interface would be as simple as:
OutputStream<byte[]> get(K)
put(K, InputStream<byte[]>)

the Map<K,V> facade simply 'marshalls' values to byte arrays and calls the
'base' interface.

This way, you get rid of any buffering from the very beginning and give
streams to cache stores... (You actually replace byte arrays by
piped(in/out)putstreams in your futures)...

Btw, I can assure you that some cache store maintainers will be super happy
to receive and produce streams ;-)

my 2 cents...
