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.
JSON representation
{"projectId": string,"namespaceId": string,}
Fields
projectId
string
The ID of the project to which the entities belong.
namespaceId
string
If not empty, the ID of the namespace to which the entities belong.
