![]() When starting each node, use the -locality flag to describe the node's location, for example, -locality=region=west,zone=us-west-1. For more details about stores, see Start a Node. Likewise, if a machine has multiple disks or SSDs, run one node with multiple -store flags and not one node per disk. Since CockroachDB replicates across nodes, running more than one node per machine increases the risk of data loss if a machine fails. This is especially crucial for multi-region deployments.Īlso keep in mind some basic topology recommendations: When planning your deployment, it's important to carefully review and choose the topology patterns that best meet your latency and resiliency requirements. ![]() ![]() This page provides important recommendations for production deployments of CockroachDB.
