VayuAPI Features

Performance & Concurrency

  • Ultra-low latency: Response times under 0.5 microseconds
  • Async-first: Built on asyncio and Starlette for maximum concurrency
  • Native Concurrency: Thread/process pools, semaphores, connection pooling
  • Low Overhead: Minimal abstractions, optimized request/response cycle
  • Zero-Copy Operations: Efficient memory usage where possible
  • Faster than FastAPI: Optimized routing and middleware pipeline
  • Thread Pool Executor: Offload blocking I/O without blocking event loop
  • Process Pool Executor: True parallelism for CPU-bound tasks (bypasses GIL)
  • Semaphores: Control concurrent access to limited resources
  • Connection Pooling: Reuse database connections efficiently
  • Async Caching: LRU cache for frequently accessed data
  • Request Batching: Optimize database queries

Concurrency Examples

# Thread Pool for blocking I/O (100+ RPS vs 0.2 RPS)
from vayuapi import run_in_thread

@app.get("/fast")
async def non_blocking_operation():
    result = await run_in_thread(blocking_task, arg)
    return {"done": True}

# Process Pool for CPU-intensive tasks (bypasses GIL)
from vayuapi import run_in_process

@app.post("/compute")
async def compute(data: list):
    result = await run_in_process(cpu_intensive_task, data)
    return {"result": result}

# Semaphores for resource limiting
from vayuapi import Semaphore

db_semaphore = Semaphore(10)  # Max 10 concurrent DB connections

@app.get("/query")
async def query_database():
    async with db_semaphore:
        return await database.query()

)

# JWT Authentication
jwt_handler = JWTHandler(
    secret_key=os.getenv("SECRET_KEY"),
    algorithm="HS256",
    access_token_expire_minutes=30
)

# Encryption for sensitive data
aes = AESEncryption(key=os.getenv("ENCRYPTION_KEY"))
encrypted_data = aes.encrypt(sensitive_info)

@app.post("/login")
async def login(username: str, password: str):
    if verify_credentials(username, password):
        token = jwt_handler.create_access_token(data={"sub": username})
        return {"access_token": token}
