### Basic Messaging
Get started with simple message production and consumption:
```rust
use pilgrimage::broker::distributed::{DistributedBroker, DistributedBrokerConfig};
use std::net::SocketAddr;
use std::time::Duration;
#[tokio::main]
async fn main() -> Result<(), Box> {
println!("๏ฟฝ Basic Messaging Example");
// Create distributed broker configuration
let config = DistributedBrokerConfig::new(
"broker1".to_string(),
"127.0.0.1:8080".parse::()?,
Duration::from_secs(30),
);
// Initialize broker
let mut broker = DistributedBroker::new(config, None).await?;
broker.start().await?;
println!("โ
Broker started successfully");
// Add message handling logic here
tokio::time::sleep(Duration::from_secs(2)).await;
Ok(())
}
```
### Advanced Performance Optimization
Leverage zero-copy operations and memory pooling for maximum throughput:
```rust
use pilgrimage::broker::performance_optimizer::{
ZeroCopyBuffer, MemoryPool, BatchProcessor, PerformanceOptimizer
};
#[tokio::main]
async fn main() -> Result<(), Box> {
// Zero-Copy Buffer Operations
let mut buffer = ZeroCopyBuffer::new(1024);
buffer.write(b"High performance message");
let slice = buffer.slice(0, 26)?;
println!("Zero-copy slice: {:?}", slice.as_ref());
// Memory Pool Usage
let pool = MemoryPool::new(100, 1024); // 100 buffers of 1KB each
let buffer = pool.acquire(512).await?;
println!("Pool stats: {:?}", pool.stats());
pool.release(buffer).await;
// Batch Processing
let mut batch_processor = BatchProcessor::new(10, true); // batch size 10 with compression
for i in 0..25 {
let message = format!("Batch message {}", i);
batch_processor.add_message(message.into_bytes()).await?;
}
if let Some(batch) = batch_processor.flush().await? {
println!("Processed batch with {} messages", batch.message_count());
}
// Performance Monitoring
let optimizer = PerformanceOptimizer::new(1000, 100, true);
let metrics = optimizer.get_metrics().await;
println!("Throughput: {} msg/s, Memory usage: {} bytes",
metrics.throughput, metrics.memory_usage);
Ok(())
}
```
### Dynamic Scaling Usage
Configure automatic scaling and intelligent load balancing:
```rust
use pilgrimage::broker::dynamic_scaling::{
AutoScaler, LoadBalancer, LoadBalancingStrategy
};
#[tokio::main]
async fn main() -> Result<(), Box> {
// Auto-Scaling Configuration
let auto_scaler = AutoScaler::new(2, 10); // min 2, max 10 instances
// Start monitoring and scaling
auto_scaler.start_monitoring().await?;
// Check current scaling status
let status = auto_scaler.get_scaling_status().await;
println!("Current instances: {}, Target: {}",
status.current_instances, status.target_instances);
// Load Balancer Setup
let mut load_balancer = LoadBalancer::new(LoadBalancingStrategy::RoundRobin);
// Add brokers to the load balancer
load_balancer.add_broker("broker1", "127.0.0.1:9092").await?;
load_balancer.add_broker("broker2", "127.0.0.1:9093").await?;
load_balancer.add_broker("broker3", "127.0.0.1:9094").await?;
// Route messages with load balancing
for i in 0..10 {
if let Some(broker) = load_balancer.get_next_broker().await {
println!("Routing message {} to {}", i, broker.id);
}
}
// Switch to least connections strategy
load_balancer.set_strategy(LoadBalancingStrategy::LeastConnections).await;
// Monitor cluster health
let health = load_balancer.cluster_health().await;
println!("Healthy brokers: {}/{}", health.healthy_count, health.total_count);
Ok(())
}
```

## ๐ฅ๏ธ CLI Interface
Pilgrimage provides a powerful command-line interface for managing brokers and messaging operations:
### ๐ Quick Start
```bash
# Start a broker
cargo run --bin pilgrimage -- start --id broker1 --partitions 4 --replication 2 --storage ./data
# Send a message
cargo run --bin pilgrimage -- send --topic events --message "Hello Pilgrimage!"
# Consume messages
cargo run --bin pilgrimage -- consume --id broker1 --topic events
# Check broker status
cargo run --bin pilgrimage -- status --id broker1
```
### ๐ Available Commands

let message = Message::new("test_topic", b"test_data");
broker.send_message(message).await.unwrap();
let received = broker.consume_message("test_topic", 0).await.unwrap();
assert_eq!(received.data(), b"test_data");
}
```
3. **Performance Testing**
```rust
#[bench]
fn bench_message_throughput(b: &mut Bencher) {
let broker = setup_test_broker();
b.iter(|| {
for i in 0..1000 {
let message = Message::new("bench_topic", format!("message_{}", i).as_bytes());
broker.send_message(message).unwrap();
}
});
}
```
#### Debugging & Profiling

### Performance Optimizer Configuration
```rust
use pilgrimage::broker::performance_optimizer::PerformanceOptimizer;
// Create optimizer with custom settings
let optimizer = PerformanceOptimizer::new(
1000, // Memory pool size (number of buffers)
100, // Batch size for message processing
true // Enable compression
);
// Configure memory pool settings
let pool = MemoryPool::new(
500, // Pool capacity
1024 // Buffer size in bytes

## Version increment on release
- The commit message is parsed and the version of either major, minor or patch is incremented.
- The version of Cargo.toml is updated.
- The updated Cargo.toml is committed and a new tag is created.
- The changes and tag are pushed to the remote repository.
The version is automatically incremented based on the commit message. Here, we treat `feat` as minor, `fix` as patch, and `BREAKING CHANGE` as major.
