Requirements for a K-Safe Physical Schema Design

Database Designer automatically generates designs with a K-safety of 1 for clusters that contain at least three nodes. (If your cluster has one or two nodes, it generates designs with a K-safety of 0. You can modify a design created for a three-node (or greater) cluster, and the K-safe requirements are already set.

If you create custom projections, your physical schema design must meet the following requirements to be able to successfully recover the database in the event of a failure:

You can use the MARK_DESIGN_KSAFE function to find out whether your schema design meets requirements for K-safety.
