The use of such vectors may seem very heavy as soon as one is concerned with a distributed system on a large number of processes. The paper proves that vectors of this length are necessary to characterize causa
This is because factors like - clock drift, network latency, and varying processing speeds lead to discrepancies in timekeeping - which can add up over time. These inconsistencies make it unreliable to use physical timestamps for ordering events globally in a distributed system. Logical clocks ...

NOTE: Actual meaning of logical clock is different it means mechanism for capturing chronological and causal relationships in a distributed system. Distributed systems may have no physically synchronous global clock. Advantages: 1.Daily exercise of brain. ...
Fortunately, there’s a tight little algorithm that does a pretty good approximation of telling you “the order in which events happened” in a distributed system: theHybrid Logical Clock (HLC). Let’s be clear up-front about the promises this clock is making; it cannot divine the actual ...
Lamport clocks: Objective We seek a clock time C(a) for every event a Clock condition: If a b, then C(a) < C(b) Plan: Tag events with clock times; use clock times to make distributed system correct The Lamport Clock algorithm Each process Pi maintains a local clock Ci Before ...

Argument 4: Distributed computing favors logical clock over physical ones, because we are only interested in event ordering anyway. Conclusion Using physical time might seem convenient at first, but it turns out to be a naive solution. In a distributed environment, perfect system time synchronization...
