Building distributed systems is not without its challenges. Some of the key challenges include:
:
: Maintains a constant number of partitions to ensure stable data-to-node mapping as the cluster grows or shrinks. patterns of distributed systems unmesh joshi pdf
If the leader fails, a new one must be chosen. However, the "Split Brain" problem—where two nodes think they are the leader—is catastrophic. Building distributed systems is not without its challenges
: A monotonically increasing number used to distinguish newer leaders from older ones after a network partition. patterns of distributed systems unmesh joshi pdf
