Retry mechanisms help distributed systems

Short summary

Retry mechanisms handle temporary failures in distributed systems by configuring maxAttempts, exponential backoff, and jitter. Exponential backoff gives failing services recovery time, while jitter prevents the thundering herd problem where simultaneous retries cause cascading failures. Each configuration parameter solves a specific production failure pattern—proper retry design is critical infrastructure.

• •Temporary failures (network glitches, timeouts, service restarts) often recover within seconds if retried
• •Exponential backoff rests failing services; jitter spreads retry requests to prevent thundering herd crashes
• •Each retry config option (maxAttempts, shouldRetry, onRetry) exists because engineers hit real production walls
