 * The SDK assumes that the persistence is only being used by a single instance
 * of the SDK per SDK key (two different SDK instances, with 2 different SDK
 * keys could use the same persistence instance).
 *
 * The SDK, with correct usage, will not have overlapping writes to the same
 * key.
 *
 * This interface does not depend on the ability to list the contents of the
 * store or namespaces. This is to maintain the simplicity of implementing a
 * key-value store on many platforms.
