partition_id |
Entities are partitioned into subsets, currently identified by a project ID and namespace ID. Queries are scoped to a single partition. |
path |
Sequence[
The entity path. An entity path consists of one or more elements composed of a kind and a string or numerical identifier, which identify entities. The first element identifies a *root entity*, the second element identifies a *child* of the root entity, the third element identifies a child of the second entity, and so forth. The entities identified by all prefixes of the path are called the element's *ancestors*. A path can never be empty, and a path can have at most 100 elements. |
