FallbackInfo
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
Informasi yang terkait dengan cara dan alasan penggunaan hasil penggantian. Jika kolom ini disetel, artinya server menggunakan mode pemilihan rute yang berbeda dari mode pilihan Anda sebagai penggantian.
| Kolom |
routingMode |
enum (FallbackRoutingMode)
Mode pemilihan rute yang digunakan untuk respons. Jika penggantian dipicu, mode tersebut mungkin berbeda dengan preferensi pemilihan rute yang ditetapkan dalam permintaan klien asli.
|
reason |
enum (FallbackReason)
Alasan respons penggantian digunakan, bukan respons asli. Kolom ini hanya diisi saat mode penggantian dipicu dan respons penggantian ditampilkan.
|
FallbackRoutingMode
Mode pemilihan rute sebenarnya yang digunakan untuk respons penggantian yang ditampilkan.
| Enum |
FALLBACK_ROUTING_MODE_UNSPECIFIED |
Tidak digunakan. |
FALLBACK_TRAFFIC_UNAWARE |
Menunjukkan bahwa TRAFFIC_UNAWARE RoutingPreference |
FALLBACK_TRAFFIC_AWARE |
Menunjukkan bahwa TRAFFIC_AWARE RoutingPreference |
FallbackReason
Alasan menggunakan respons penggantian.
| Enum |
FALLBACK_REASON_UNSPECIFIED |
Tidak ada alasan penggantian yang ditentukan. |
SERVER_ERROR |
Terjadi error server saat menghitung rute dengan mode pemilihan rute pilihan Anda, tetapi kami dapat menampilkan hasil yang dihitung dengan mode alternatif. |
LATENCY_EXCEEDED |
Kami tidak dapat menyelesaikan penghitungan dengan mode pemilihan rute pilihan Anda tepat waktu, tetapi kami dapat menampilkan hasil yang dihitung oleh mode alternatif. |
