Overview

• Research examines limitations of the CAP theorem in distributed systems
• Introduces “Partial Progress” as a key consideration alongside consistency, availability, and partition tolerance
• Analyzes Cassandra’s distributed database system behavior under network partitions
• Proposes new framework for understanding distributed system tradeoffs

Plain English Explanation

The CAP theorem states that distributed systems can only guarantee two out of three properties: consistency, availability, and partition tolerance. This research suggests we’ve overlooked something important – partial progress, which means a system can keep working at reduc…
