Consensus Algorithm
Software Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A consensus algorithm is a protocol used in distributed systems to achieve agreement on a single data value among multiple processes or nodes. It ensures that even if some nodes fail, the system can still agree on a consistent state.
Example in context
“The database cluster relies on a consensus algorithm to maintain strong consistency across all replicas during write operations.”
“Veritabanı kümesi, yazma işlemleri sırasında tüm yedekler arasında güçlü tutarlılık sağlamak için bir uzlaşı algoritmasına güvenir.”
Where engineers use it
Consensus algorithms are used in distributed databases and replicated state machines to coordinate updates. An engineer must understand them when designing fault-tolerant systems to prevent data divergence and guarantee safety properties.
Synonyms: consensus protocol, distributed consensus
Practice: can you use “Consensus Algorithm” at work?
You are the architect of a multi-region database. During a network partition, some replicas become unreachable. How would you configure the consensus algorithm to maintain availability and consistency?
