  value: "String",
  exists: false,
}

Specifies the conditions under which data should be updated. If an update condition is specified for a request, the data will only be updated if the condition is satisfied. For example, if an attribute with a specific name and value exists, or if a specific attribute doesn't exist.

• #name ⇒ String
