# ACE Documentation Index

**ACE v0.1.0** - Adaptive Concurrency Engine

---

## Getting Started (30 minutes)

1. **[Install](README.md#installation)** - `pip install ace-concurrency`
2. **[Quick Start](README.md#quick-start)** - Run async example
3. **[Configuration](README.md#configuration)** - Customize AIMD parameters
4. **[Observability](README.md#observability)** - Monitor via JSON logs

---

## Core Concepts

### System Signals

Monitored every 2 seconds:

- CPU utilization (%)
- Memory utilization (%)
- Event loop lag (milliseconds)
- Queue depth (tasks waiting)
- Kafka consumer lag (optional)

### Decision Types

- **INCREASE:** Proactive (low load) or reactive (queue catching up)
- **DECREASE:** High CPU/memory or queue overflow
- **HOLD:** Steady state, system healthy

---

## Integration Guides

### Async Tasks

**Best for:** I/O-bound work (API calls, database queries)

```python
async with ACEAsyncioManager(config) as mgr:
    await mgr.submit(your_async_task())
```

### Thread Pools

**Best for:** CPU-bound work (calculations, data processing)

```python
with ACEThreadPoolManager(config) as mgr:
    mgr.submit(your_sync_function)
```

### Kafka Consumers

**Best for:** Event streaming with backpressure

```python
async with ACEKafkaConsumerManager(config, "topic") as mgr:
    await mgr.process_async(handler)
```

---

## Configuration Guide

### Basic Configuration

```python
config = AIMDConfig(
    min_limit=1,
    max_limit=100,
    initial_limit=10,
)
```

### Advanced Configuration

```python
config = AIMDConfig(
    # Concurrency bounds
    min_limit=5,
    max_limit=200,
    initial_limit=50,

    # AIMD parameters
    increase_step=5,           # More aggressive increase
    decrease_factor=0.3,       # Faster decrease

    # Thresholds (CPU/Memory %)
    cpu_threshold=75.0,
    memory_threshold=80.0,
    cpu_increase_threshold=30.0,      # Earlier proactive scaling
    memory_increase_threshold=40.0,

    # Timing (seconds)
    adjustment_interval=1,     # More frequent decisions
    cooldown_period=10,        # Longer wait after decrease
)
```

## Monitoring & Observability

### Structured JSON Logs

```json
{
  "timestamp": "2026-01-16T14:30:45Z",
  "level": "INFO",
  "message": "AIMD decision",
  "decision": "INCREASE",
  "current_limit": 10,
  "new_limit": 12,
  "signals": {
    "cpu_percent": 35.5,
    "memory_percent": 42.3,
    "queue_depth": 5,
    "event_loop_lag_ms": 2.1
  }
}
```

### Metrics to Track

- Current concurrency limit
- Active task count
- CPU/Memory utilization
- Decision frequency (INCREASE/DECREASE/HOLD)
- System response time

## Common Tasks

### Task: Change concurrency limits

```python
# During runtime (if you need dynamic adjustment)
with ACEAsyncioManager(config) as mgr:
    # Limits controlled automatically by AIMD
    # To override, set directly:
    # Not recommended - trust AIMD algorithm
    pass
```

### Task: Access current limit

```python
async with ACEAsyncioManager(config) as mgr:
    print(f"Current limit: {mgr.current_limit}")
    print(f"Active tasks: {mgr.active_tasks}")
```

### Task: Custom signal collection

```python
from ace.core.signals import SignalCollector

collector = SignalCollector()
collector.set_queue_depth(len(my_queue))
signals = await collector.collect_all_async()
```

### Task: Batch multiple AIMD managers

```python
# Multiple independent managers (recommended for isolation)
async with ACEAsyncioManager(config1) as mgr1:
    async with ACEAsyncioManager(config2) as mgr2:
        # Separate control loops
        pass
```
