That link has comments between anna and faster authors. The best part being:

> There are two high-level design goals that separate Anna and FASTER.

> First of all, for Anna, we set out to explore an execution model that’s truly coordination-free; each thread accepts requests, performs computation and sends out response without communicating or waiting for other threads. We believe having a coordination-free execution model is the key to fully exploiting multi-core parallelism within a single machine, and scale out smoothly to a distributed setting. We acknowledge that the fundamental caveat of having a coordination-free execution model is that strong consistencies (linearizability, serializability) are not achievable. Anna instead offers a wide-spectrum of coordination-free consistencies taxonomized in Bailis’s HAT paper (http://www.vldb.org/pvldb/vol7/p181-bailis.pdf).

> In addition, in Anna we focus on exploring a unified architecture that works at any scale, from a single multi-core machine to NUMA to a geo-distributed setting. Under this goal, architectures that rely on shared memory within a machine (including FASTER) need to be redesigned as we move to a distributed setting. This complicates the software, and can introduce challenges in maintaining consistency as the execution model within nodes and across nodes are now different.

> Anna currently focuses on workloads that fit in memory. For larger-than-memory data, we believe Anna can benefit from the hybrid-logging technique in FASTER for efficiently persisting data to stable storage.
