Abstract
The disclosure herein describes placing a delta component of a base component in a target fault domain. A delta component associated with a base component is generated. The generation includes selecting a first fault domain as a target fault domain for the delta component based on the first fault domain including a witness component associated with the distributed data object of the base component. Otherwise, the generation includes selecting a second fault domain as the target fault domain based on the second fault domain including at least one data component that includes a different address space than the base component. Otherwise, the generation includes selecting a third fault domain as the target fault domain based on the third fault domain being unused. Then, the delta component is placed on the target fault domain, whereby data durability of the distributed data object is enhanced, and available fault domains are preserved.
