FLP Impossibility
Understand the FLP impossibility theorem which explains why no consensus algorithm can guarantee termination in asynchronous distributed systems with at least one faulty node. This lesson helps you grasp the inherent limitations of consensus solutions and prepares you to reason about design trade-offs and fault tolerance strategies in distributed system consensus.
We'll cover the following...
Researchers have found many different solutions to the consensus problem, but they have also found important constraints that impose some limitations on the possible solutions.
We should note that it’s beneficial to know the limits of the available solutions to a problem, and the research community has benefited massively from this.
We will start by first explaining these limitations and ...
