Hi,
I'm looking to know how to calculate shipping cost for sending pages to remote sites of a distributed database. The explanation I have is:
"Tuples are shipped in units of one page by waiting for a page to be filled before sending a message from processor i to processor j"
If it helps, each processor have 100 buffer pages of 4000 bytes each, and each relation contains 20 bytes tuples. There are 10 processors.
How do I calculate the cost of shipping? Is there a general algorithm or formula? Do I need any more information than that? I do have other details such as pages per relations and the repartition, but I'm looking for a generic way to do things.
Thank you, any help is appreciated.
