We are currently working in project where we want to use Voldemort to store some ip packages.

1) What would be the best way to identify a single package ? we thought about a key which consist of the time..since this would be unique

Thank you very much in advance!

This is a data modeling/structure question, not really a Voldemort question. This question is probably best answered by you, yourself, not us. But, if you can clarify what you mean by "ip packages" (I have never heard this term before), perhaps we can give you some pointers on how to ensure key uniqueness without accidental overwrites.

Hi Brendan,

thank you for fast reply. I agree on that point with you that it's a data modelling question. I meant ip packet (TCP/IP packets).

I see. Well, in that case, time would not be unique enough. You could do a union of timestamp+TCP sequence number. But, even that might not be unique enough. You could still have a collision with that formula. Ultimately, it depends on what you care about and how you want to be able to recall the information. What is the most relevant piece of information in the packet? Source port? Destination port? TCP Flag? You might want the key to be a union of the most relevant pieces of information.

Perhaps if you explained the use case a bit, we could recommend an ideal way of storing and recalling the information.

We decided to do a union of timestamp (micros) and packet length. Having someone replying to a question is always helpful. Thank you very much!
