gRPC & High-Performance System Design

08. 8 Ta Real-World Demo Loyiha va Yakuniy Masterclass Xulosasi

Tabriklaymiz! Siz ushbu masterclass orqali zamonaviy yuqori yuklamali tizimlar (High-Performance System Design) ning eng chuqur sirlarini o'rganib chiqdingiz.

Nazariya o'z yo'liga, ammo haqiqiy muhandislik — bu ishlaydigan koddir! Barcha 8 ta darslik bo'yicha to'liq, sinovdan o'tgan va ishlab turgan namunaviy loyihalar maxsus ochiq repozitoriyga joylashtirildi:

Har Bir Loyihaning Mohiyati

1. 01-unary-auth-profile

  • Go: Standart gRPC server, foydalanuvchi profilini qaytarish.
  • Swift: Swift 6 async/await orqali timeoutli so'rov yuborish.
  • Maqsad: Nega JSON 4 barobar ko'p trafik va 11 barobar ko'p protsessor sarflashini ko'rish.

2. 02-server-streaming-chat

  • Go: Doimiy ochiq gRPC stream orqali xabarlarni uzluksiz oqizish.
  • Swift: AsyncThrowingStream orqali SwiftUI ro'yxatini reaktiv yangilash.
  • Maqsad: WebSocket o'rniga gRPC Server-Streaming qulayligini his qilish.

3. 03-bidirectional-geotracking

  • Go: Har bir mashinaning koordinatasini qabul qilib, atrofdagi boshqa haydovchilarga uzatish.
  • Swift: SwiftUI Map ustida jonli taksi radari (avtomobil harakatlari).
  • Maqsad: Bir vaqtning o'zida ham yozish, ham o'qish (Bi-directional Stream).

4. 04-client-streaming-telemetry

  • Go: 100 ta voqea tugagandan so'ng umumiy tasdiq (Digest Response) qaytarish.
  • Swift: Mobil ilovada xotira to'lmasligi uchun cheklangan ring bufer bilan ishlash.
  • Maqsad: High-frequency event logging.

5. 05-fintech-mtls-interceptors

  • Go: tls.RequireAndVerifyClientCert orqali begona so'rovlarni TLS darajasida rad etish.
  • Swift: Dynamic HMAC imzo va apparat kalitlari bilan so'rovni boyitish.
  • Maqsad: Payme, Click yoki Bank ilovalarining xavfsizligi.

6. 06-flatbuffers-zero-copy

  • Go: FlatBuffers binar paketini xotirada yasash (flatbuffers.Builder).
  • Swift: ByteBuffer yordamida obyekt yaratmasdan, xotiradan O(1) vaqtda o'qish.
  • Maqsad: O'yinlar, 3D grafika va o'ta tezkor ma'lumotlar oqimi.

7. 07-http3-quic-transport

  • Go: quic-go/http3 orqali UDP ustida ishlovchi server.
  • Swift: Apple Network.framework va URLSession Connection Migration konfiguratsiyasi.
  • Maqsad: Wi-Fi dan LTE ga o'tganda aloqaning uzilmasligini tushunish.

8. 08-offline-sqlite-wal-sync

  • Go: Batch Ingestion endpoint — 500 ta voqeani 1 ta SQL tranzaksiyada yozish.
  • Swift: SQLite WAL rejimida lokal saqlash va NWPathMonitor bilan internet chiqqanda sinxronizatsiya.
  • Maqsad: To'liq oflayn ishlovchi chidamli ilova yaratish.

🎯 Yakuniy Xulosa: Siz Endi Tizim Arxitektorisiz!

Ko'plab dasturchilar butun umri davomida faqatgina tugma bosilganda oddiy REST JSON API ga so'rov yuborish bilan cheklanib qolishadi. Ular server orqasida nimalar sodir bo'layotganini, batareya nima uchun tez tugayotganini yoki ilova nega qotayotganini tushunishmaydi.

Siz esa endi:

  • Baytlar darajasida (Varint, Wire types, Zero-Copy) fikrlay olasiz;
  • Tarmoq darajasida (HTTP/2, HTTP/3 QUIC, TCP HoL Blocking, Connection Migration) muammolarni yecha olasiz;
  • Xavfsizlik darajasida (mTLS, Secure Enclave, HMAC) bank standartlarini joriy qila olasiz;
  • Arxitektura darajasida (SQLite WAL, Ring Buffer, Client/Server Streaming) millionlab foydalanuvchilar yuklamasiga bardosh beradigan tizimlarni qura olasiz!

O'rganishdan va katta cho'qqilarni zabt etishdan hech qachon to'xtamang! 🚀
