Overview#

A distributed database system demonstrating data consistency across multiple worker nodes using a central coordinator and the two-phase commit protocol. Implements the classic distributed systems challenge of maintaining ACID properties across network boundaries.

Key Concepts#

• Implemented two-phase commit (2PC) protocol for distributed transactions
• Built coordinator-worker architecture with clear separation of concerns
• Created client interface supporting GET, SET, and database verification commands
• Developed consistency verification to ensure all workers maintain identical state
• Developed stress testing commands (rapidset, multiset) for consistency validation
• Handled worker timeout and failure scenarios gracefully
