What is a Leader Election?
Leader election is a process in distributed computing where nodes (computers or devices) choose one among themselves to act as a coordinator or leader. The leader is responsible for making decisions, coordinating actions, and ensuring the system’s smooth operation. This mechanism helps maintain order, manage resources efficiently, and ensure fault tolerance in distributed systems, even in the presence of failures or network issues.
Leader Election in System Design
Leader election is a critical concept in distributed system design, ensuring that a group of nodes can select a leader to coordinate and manage operations effectively. In distributed systems, having a single leader can simplify decision-making and coordination, leading to more efficient and reliable operations.
