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.
