Preparation for Recitation 20
Read the paper Manageability,
Availability and Performance in Porcupine: A Highly Scalable Internet
Mail Service by Yasushi Saito, Brian Bershad and Hank Levy.
As you are reading the paper, think about the following question:
How do Porcupine nodes recover the 256-entry user map after a crash?
What configurations might require a user map that contains more than
256 entries? Do you think the user map should still be soft state
in those configurations?
