Using exponential backoff alone is more effective in handling retries in a distributed system than combining exponential backoff with jitter for managing transient failures.
True
False
The statement is false. While exponential backoff is a strategy that progressively increases the wait time between consecutive retry attempts, thus reducing the load on the server and giving it time to recover, it might still lead to the so-called 'retry-storm' if many clients are trying to reconnect at the same intervals. By adding jitter, or randomization to the wait times, the retries are more evenly spread out, which further decreases the likelihood of overwhelming the system. This combined approach reduces the chance of synchronized retries across multiple instances and is generally acknowledged as a best practice for fault-tolerant design within distributed systems.
