Re: JavaSpace Implementations

Hi,

It would be useful if you could be more specific about your needs.
Failover and replication are simply features and there are a multitude
of ways to implement them and some approaches work better than others in
various scenarios.

Further, depending on your exact needs, you may need to carefully select
a hardware configuration.

So:

(1)     What speed of failover do you require?

(2)     Why do you need replication?  Presumably you don't want to lose Entry's?

(3)     How many Entry's do you plan to have in your JavaSpace at any
particular time?

(4)     Are you using the JavaSpace for messaging or to hold state long term
like an RDBMS?

(5)     How many clients do you anticipate having connected to the JavaSpace?

Declaration:  I am the author of Blitz so I have my own biases!  I'm
also asking the above questions to try and understand what I would
implement were I to do it.

I am not aware of an opensource implementation that addresses these
issues.  GigaSpaces does but, obviously, that's a commercial product
with associated cost models etc.

Best wishes,

Dan.
