- Deprecated Fields
  Field and Description
  com.google.appengine.api.datastore.DatastoreConfig.DEFAULT Use `DatastoreServiceConfig` instead.
  com.google.appengine.api.datastore.FetchOptions.DEFAULT_CHUNK_SIZE Instead of using DEFAULT_CHUNK_SIZE, do not specify a chunk size.
  com.google.appengine.api.utils.SystemProperty.instanceReplicaId Use `com.google.appengine.api.servers.ServerService#getCurrentInstance()`
  com.google.appengine.api.datastore.Query.KIND_METADATA_KIND
  com.google.appengine.api.datastore.Query.NAMESPACE_METADATA_KIND
