/**
 * 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.
