Thespis: Actor-Based Middleware for Causal Consistency

TL;DR

This paper surveys current causal consistency data stores and introduces Thespis, an actor-based middleware that implements causal consistency over standard data stores, enhancing scalability and modularity.

Contribution

It presents Thespis, a novel middleware leveraging the Actor model to achieve causal consistency, bridging the gap between theoretical models and practical data store implementations.

Findings

Thespis effectively enforces causal consistency in standard data stores.

Actor-based design improves modularity and scalability.

Survey highlights current challenges in causal consistency implementations.

Abstract

This paper provides a survey of the current state of the art in Causally-Consistent data stores. Furthermore, we present the design of Thespis, a middleware that innovatively leverages the Actor model to implement causal consistency over an industry-standard data store.
