Aşama 2: Ingest Servisi İşlemesi

Ingest Servisi, HTTP POST ederilen paketi alır, doğrular ve Redis'e yazar.

Işlem Adımları:

1. JSON parse
2. CPS şeması doğrulama (Info, Device, Payload blokları)
3. device_id (ID) CRC8 kontrolü
4. Duplicate check (Redis)
5. Kalıcı raw DB yazımı
6. Normalize edilmiş device_buffer oluşturma (ve CPS kayıt formattan canonical forma dönüştürme)
7. Kafka tetikleme

Örnek Dönüşüm (vektör -> canonical şema):

• VRMS: [220.006, 223.792, 221.671] -> VRMS_R: 220.006, VRMS_S: 223.792, VRMS_T: 221.671
• IRMS: [3.995, 4.073, 3.887] -> IRMS_R: 3.995, IRMS_S: 4.073, IRMS_T: 3.887
• P: [746.184, 764.792, 777.262] -> P_R: 746.184, P_S: 764.792, P_T: 777.262

Sonuç: device_buffer state after ingest:

Neler Oldu:

• ✅ Paket geçerli ve duplicate değil
• ✅ Raw DB'ye wire payload yazıldı (raw_id: 2841023)
• ✅ device_buffer oluşturuldu ve Redis'e yazıldı
• ✅ CPS payload normalize edildi (Info, Device, Payload → buffers.measurements + device_metadata)
• ✅ Harmonic vector alanları canonical şemada açıldı (IHARM_*_3/5/7/9, VHARM_*_3/5/7/9)
• ℹ️ Bu örnekte vektörde olmayan harmonikler (örn. *_11) canonical state'e yazılmadı
• ✅ Harmonik veriler korundu (geleceğe yönelik analiz için)
• ℹ️ buffers.synthesis ve buffers.window henüz boş (sonraki servisler doldurur)

Aşama 3: Stream Servisi İşlemesi

Stream Servisi, ingest event'i consume eder. Parçalı metrikleri birleştirir, stream_id atar ve finalize eder.

Kafka event (ingest → stream):

{
  "event": "ingest.accepted.v1",
  "context": {
    "device_id": "64000000C466EF70",
    "device_time": "2026-04-13T11:18:09Z",
    "received_at": "2026-04-13T11:18:10Z"
  }
}

Stream Servisi:

1. device_buffer okuyor
2. stream_id atıyor (auto-increment: 10248764)
3. Metadata ekleniyor
4. Kalıcı stream tablosuna yazıyor

device_buffer state (stream sonrası — Ingest + Stream birlikte):

{
  "device_id": "64000000C466EF70",
  "device_time": "2026-04-13T11:18:09Z",
  "current_stage": "streamed",
  "ingest": {
    "ingest_time": "2026-04-13T11:18:10Z",
    "is_valid": true,
    "raw_id": 2841023,
    "process_time_ms": 8
  },
  "stream": {
    "stream_id": 10248764,
    "stream_time": "2026-04-13T11:18:11Z",
    "process_time_ms": 13
  },
  "buffers": {
    "measurements": { /* ... tüm measurements ... */ },
    "synthesis": {},
    "window": {}
  }
}

Neler Oldu:

• ✅ Ingest verileri korundu
• ✅ Stream metadata eklendi (stream_id, stream_time)
• ✅ Kalıcı stream tablosuna yazıldı

---

Aşama 4: Calibration Servisi İşlemesi

Calibration Servisi, raw measurements'ı device-specific calibration rule'ları ile kalibre eder.

Kalibrasyon Kuralı:

{
  "device_id": "64000000C466EF70",
  "ct_ratio": 1.0,
  "vt_ratio": 1.0,
  "created_at": "2025-12-01T00:00:00Z"
}

Not: Bu cihaz doğrudan ölçüm yapıyor (CT/VT oranları 1:1), bu nedenle kalibrasyon minimal.

device_buffer state (calibration sonrası — Ingest + Stream + Calibration):

{
  "device_id": "64000000C466EF70",
  "device_time": "2026-04-13T11:18:09Z",
  "current_stage": "calibrated",

    "ingest_time": "2026-04-13T11:18:10Z",
    "is_valid": true,
    "raw_id": 2841023,
    "process_time_ms": 8
  },
  "stream": {
    "stream_id": 10248764,
    "stream_time": "2026-04-13T11:18:11Z",
    "process_time_ms": 13
  },
  "calibration": {
    "calibration_time": "2026-04-13T11:18:12Z",
    "process_time_ms": 11,

  },
  "buffers": {
    "measurements": { /* ... tüm measurements korundu ... */ },
    "synthesis": {},
    "window": {}
  }
}

Neler Oldu:

• ✅ Ingest + Stream verileri korundu
• ✅ Calibration metadata eklendi
• ✅ Measurements'lar kalibre edildi (1:1 oranında değişim yok)

---

Aşama 5: Raw Writer Servisi İşlemesi

Raw Writer, kalibre edilmiş ölçümleri typed tablo'lara yazar.

Yazılan Tablolar:

• measurements_voltage ← VRMS (3 faz)
• measurements_current ← IRMS (3 faz) + IFUND + IHARM + IPEAK
• measurements_power ← P, Q, S (aktif, reaktif, görünür güç)
• measurements_energy ← AE (enerji sayacı)
• measurements_device ← STATUS, PCB_T/H, RSSI, FQ
• measurements_harmonics ← VHARM, IHARM (voltaj/akım harmonikleri)
• measurements_register ← Device metadata (firmware, ICCID)

device_buffer state (raw writer sonrası — Ingest + Stream + Calibration + Raw Writer):

{
  "device_id": "64000000C466EF70",
  "device_time": "2026-04-13T11:18:09Z",
  "current_stage": "raw_written",

    "process_time_ms": 11,
    "ct_ratio": 1.0,
    "vt_ratio": 1.0,
    "calibrated_value_count": 3
  },
  "raw_writer": {

    "process_time_ms": 15,
    "table_write_counts": {

    }
  },
  "buffers": {
    "measurements": { /* ... tüm measurements korundu ... */ },
    "synthesis": {},
    "window": {}
  }
}

Neler Oldu:

• ✅ Ingest + Stream + Calibration verileri korundu
• ✅ Raw Writer metadata eklendi
• ✅ 7 farklı typed tablo başarıyla yazıldı
• ℹ️ Buffers hala synthesis ve window için boş

Aşama 6: Synthesis Servisi İşlemesi

Synthesis Servisi, measurements'dan derived metrics ve kalite endeksleri hesaplar:

Sentez Kuralları:

{
  "device_id": "64000000C466EF70",

      "description": "Akım toplam harmonik distorsiyonu"
    }
  ]
}

Hesaplamalar:

1. Ortalama Voltaj: (220.006 + 223.792 + 221.671) / 3 = 221.823 V
2. Ortalama Akım: (3.995 + 4.073 + 3.887) / 3 = 3.985 A
3. Toplam Güç: 746.184 + 764.792 + 777.262 = 2,288.238 W
4. Ortalama PF: (0.85 + 0.84 + 0.9) / 3 = 0.863
5. Voltaj THD (R fazı): √(2.598² + 0.951² + 4.972² + 0.205²) / 219.997 × 100 = 2.38%
6. Akım THD (R fazı): √(0.036² + 0.059² + 0.07² + 0.004²) / 3.999 × 100 = 1.92%

Aşama 7: Window Servisi İşlemesi (Sonrası)

Window Servisi, synthesis eventini consume eder. Zaman pencereleri (5-min, 1-hour vb.) hesaplayıp agregate sonuçları üretir.

Sonuç (device_buffer final state):

Hata Durumu Örneği

Eğer harmonik kalitesi çok kötüyse (THD_I > 30%) ve Synthesis başarısız olursa:

{
  "event": "synth.failed.v1",
  "context": {
    "device_id": "64000000C466EF70",
    "stream_id": 10248764
  },
  "error": {
    "failed_stage": "rule_resolution",
    "error_code": "RULE_NOT_FOUND",
    "error_message": "No active synthesis rule for device_id=64000000C466EF70",
    "retryable": false,
    "failed_at": "2026-04-13T11:18:14Z"
  }
}

İşlemler:

1. Hata DLQ (qapu.synth.dlq) yazılır
2. Ops team'e alert gönderilir
3. Manual inceleme: Kural neden missing?
4. Manual recovery: Kural assign edilir → replay trigger

---

Önemli Noktalar

1. device_buffer tüm aşamalarda ortak çalışma alanı
2. Her servis kendi bölümünü doldurur, önceki adımları okur
3. Harmonik veriler (IHARM, VHARM) korunur — gelecekteki analiz için
4. Kalite metrikleri (THD, PF, frequency) sentez aşamasında hesaplanır
5. Hata oluşursa event üretilir ve optional retry yapılır
6. Latency: Ingest → Synthesis ~63ms, Window'a kadarsa ~82ms
7. Idempotency: Aynı stream_id tekrar işlenirse aynı sonuç
8. Multi-phase measurement: 3-fazlı sistem, tüm faz verisi preserved
