Question

I needed to implement a utility server that tracks few custom variables that will be sent from any other server. To track the variables, a key value collection, either JDK defined or custom needs to be used.

Here are few considerations –

• Keeping all the variables in memory of the server all the time is memory intensive.
• This server needs to be a very lightweight server and I do not want heavy database operations.

Is there a pre-defined streaming collection which can serialize the data after a threshold memory and retrieve it on need basis?

I hope I am clear in defining the problem statement.

Please suggest if any other better approach.

Answer 1

this thing looks very promising, but is in development stage…

JDBM3
