#partition_id ⇒ Google::Apis::DatastoreV1::PartitionId

A partition ID identifies a grouping of entities. The grouping is always by project and namespace, however the namespace ID may be empty. A partition ID contains several dimensions: project ID and namespace ID. Partition dimensions:

  • May be "". - Must be valid UTF-8 bytes. - Must have values that match regex [A-Za-z\d\.\-_]1,100`If the value of any dimension matches regex. *, the partition is reserved/read-only. A reserved/read-only partition ID is forbidden in certain documented contexts. Foreign partition IDs (in which the project ID does not match the context project ID ) are discouraged. Reads and writes of foreign partition IDs may fail if the project is not in an active state. Corresponds to the JSON propertypartitionId`

Returns:

#path ⇒ Array<Google::Apis::DatastoreV1::PathElement>

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. An entity path is always fully complete: all of the entity's ancestors are required to be in the path along with the entity identifier itself. The only exception is that in some documented cases, the identifier in the last path element (for the entity) itself may be omitted. For example, the last path element of the key of Mutation.insert may have no identifier. A path can never be empty, and a path can have at most 100 elements. Corresponds to the JSON property path
