Interestingly, we find that under this new Pull model, replication schemes capture a novel tradeoff between different values of the AoI across the servers (due to the random updating processes) and different response times across the servers, which can be exploited to minimize the expected AoI at the user's side.

To the best of our knowledge, this is the first work that shows how to achieve logarithmic regret in constrained contextual bandits.
