Cockroach University: Resiliency in the Cluster

In this Cockroach University lesson titled “Resiliency in the Cluster”, you will learn about how a cluster can recover from the loss of a node. Then we’ll discuss how in larger clusters CockroachDB is able to handle fragile states by moving replicas to available nodes. In this lesson, you will learn to: •Explain how a cluster can recover from the loss of a node •Describe the circumstances under which such a recovery can happen You will also learn: •The availability guarantees of a replication factor of 3 vs. a replication factor of 5 Learn more about CockroachDB by signing up for free training at Cockroach University: https://university.cockroachlabs.com/ --------------------------------------------------------------------------------------------------------------------------- Reference Links •Rebalance and Repair in the Replication Layer: https://www.cockroachlabs.com/docs/stable/architecture/replication-layer.html (CockroachDB Docs) •Fault Tolerance And Recovery: https://www.cockroachlabs.com/docs/stable/demo-fault-tolerance-and-recovery.html (CockroachDB Docs) --------------------------------------------------------------------------------------------------------------------------- Careers: https://www.cockroachlabs.com/careers CockroachCloud: https://www.cockroachlabs.com/product/cockroachcloud/ Blog: https://www.cockroachlabs.com/blog/ Docs: https://www.cockroachlabs.com/docs/stable/ Community Slack: https://cockroa.ch/Welcome-to-Slack Twitter: https://twitter.com/CockroachDB
