Determining the Current K-Safety: Quick Tip

Posted January 15, 2019 by James Knicely, Vertica Field Chief Technologist

K-safety sets the fault tolerance in your Vertica database cluster. The value K represents the number of times the data in the database cluster is replicated. These replicas allow other nodes to take over query processing for any failed nodes.

You can view the current K-Safety of a Vertica database in several ways.

Example: dbadmin=> SELECT get_design_ksafe(); get_design_ksafe ------------------ 1 (1 row) dbadmin=> SELECT current_fault_tolerance FROM system; current_fault_tolerance ------------------------- 1 (1 row) Helpful Links:
