WebbIn "Small Cache, Big Effect: Provable Load Balancing for Randomly Partitioned Cluster Services", it is shown, theoretically and empirically, that for a distributed key-value store randomly partitioned over n back-end nodes, a front-end cache with O(n log n) items guarantees that no node will ever be overloaded.

Leonardi, and S. Traverso. Efficient analysis of caching strategies under dynamic content popularity. WebbEnsuring load balancing only requires a relatively small cache. In addition, to achieve high throughput, the front-end cache must be fast enough to keep the cluster of nodes behind it busy. The paper proves that the cache need only store O(nlogn) entries to provide good load balance, where n is the total number of back-end nodes. grand jct colorado hotelsWebbSmall Cache, Big Effect: Provable Load Balancing for Randomly Partitioned Cluster Services.
