Re: General questions about Javaspaces

Of course one thing that is perhaps more fundamentally important and
*different* about a Rio-based grid - compared to other grid implementations
is that Rio offers the capability to define performance characteristics of
the grid, and will enforce those performance target/limit definitions
dynamically.
If you need transactional throughput of X transactions per minute - Rio -
*can* enable you to implement a solution which can meet these targets.

(As an example - if a consumer process is not deemed to be consuming fast
enough - and a backlog is developing....one can add a SLA definition to tell
Rio - "when the backlog is Y large - start another competing consumer up" -
which will help to reduce the backlog. (Active dampening of a load spike). Of
course when the backlog falls to an acceptable limit - your SLA definition
can tell Rio to drop the number of Consumer instances that are running)

In an industrial/financial environment, its this kind of capability which IMHO
sets a Rio-based grid on a new level. (Its also why I use it).
