In this lecture, we study the Timestamp Ordering Protocol, a non-lock-based concurrency control technique used to ensure serializability without locks.
We cover different variations including Basic Timestamp Ordering, Strict Timestamp Ordering, and Thomas Write Rule, along with examples.
Timestamp Ordering Protocol
📌 Topics Covered
🔹 Basic Timestamp Ordering
• Read & Write rules
• Ensuring serializability
🔹 Strict Timestamp Ordering
• Avoiding cascading rollbacks
• Maintaining strict schedules
🔹 Thomas Write Rule
• Ignoring obsolete writes
• Improving concurrency
• Examples and problem-solving approach
🎯 Why this topic is important?
Timestamp-based protocols are frequently asked in GATE and provide an alternative to locking mechanisms.
🎯 Important for:
GATE CSE (Not in GATE DA)
Concurrency Control
Transaction Management
