### 🔒 Authentication & Security (✅ Production Ready)
Authentication is **disabled by default** for development. Enable it for production:
**Features:**
- ✅ **Root User Management** - Configurable root user with full permissions
- ✅ **User Management** - Create, delete, enable/disable users
- ✅ **API Key Management** - Generate, revoke, and manage API keys with expiration
- ✅ **Fine-grained Permissions** - Resource-based permissions (RabbitMQ-style)
- ✅ **Basic Auth & Bearer Token** - Support for both authentication methods
- ✅ **Audit Logging** - Track all authentication events (login, API key usage, permission denials)
- ✅ **Password Validation** - Configurable password requirements (length, complexity)
- ✅ **IP Filtering** - Restrict API keys to specific IP addresses
**Via Config File** (`config.yml`):
```yaml
auth:
enabled: true
require_auth: true
root:
username: "root"
password: "your_secure_password"
enabled: true
```
**Via Docker Environment Variables**:
```bash
docker run -d -p 15500:15500 \
-e SYNAP_AUTH_ENABLED=true \
-e SYNAP_AUTH_REQUIRE_AUTH=true \
-e SYNAP_AUTH_ROOT_USERNAME=root \
-e SYNAP_AUTH_ROOT_PASSWORD=your_secure_password \
synap:latest
```
**Using Authentication**:
```bash
# Basic Auth
curl -u root:password http://localhost:15500/kv/get/user:1
# Bearer Token (API Key)
curl -H "Authorization: Bearer sk_XXXXX..." http://localhost:15500/kv/get/user:1
# Query Parameter
curl "http://localhost:15500/kv/get/user:1?api_key=sk_XXXXX..."
```
See [Authentication Guide](docs/AUTHENTICATION.md) for complete details.
### 🔄 Replication Setup
Synap supports master-slave replication for high availability and read scaling.
#### Quick Start with Docker
```bash
# Start 1 master + 3 replicas
docker-compose up -d
# Master available at: localhost:15500
# Replica 1 at: localhost:15501
# Replica 2 at: localhost:15502
# Replica 3 at: localhost:15503
```
#### Manual Setup
**Master Node Configuration** (`config-master.yml`):
```yaml
server:
host: "0.0.0.0"
port: 15500
replication:
enabled: true
role: "master"
replica_listen_address: "0.0.0.0:15501"
heartbeat_interval_ms: 1000
max_lag_ms: 10000
buffer_size_kb: 256
replica_timeout_secs: 30
persistence:
enabled: true
wal:
enabled: true
path: "./data/wal/synap.wal"
snapshot:
enabled: true
directory: "./data/snapshots"
```
**Replica Node Configuration** (`config-replica.yml`):
```yaml
server:
host: "0.0.0.0"
port: 15500
replication:
enabled: true
role: "replica"
master_address: "master:15501" # Master's replication port
heartbeat_interval_ms: 1000
max_lag_ms: 10000
buffer_size_kb: 256
auto_reconnect: true
reconnect_delay_ms: 5000
persistence:
enabled: true
wal:
enabled: true
path: "./data/wal/synap.wal"
snapshot:
enabled: true
directory: "./data/snapshots"
```
**Start Nodes**:
```bash
# Terminal 1: Start master
synap-server --config config-master.yml
# Terminal 2: Start replica 1
synap-server --config config-replica-1.yml
# Terminal 3: Start replica 2
synap-server --config config-replica-2.yml
```
#### Usage Patterns
**Write to Master**:
```bash
# All writes go to master
curl -X POST http://localhost:15500/kv/set \
-H "Content-Type: application/json" \
-d '{"key": "user:100", "value": "Alice", "ttl": 3600}'
```
**Read from Replicas** (Load Balancing):
```bash
# Read from replica 1 (eventually consistent, ~5ms lag)
curl http://localhost:15501/kv/get/user:100
# Read from replica 2
curl http://localhost:15502/kv/get/user:100
# Read from replica 3
curl http://localhost:15503/kv/get/user:100
```
**Monitor Replication Status**:
```bash
# Check replication health on master
curl http://localhost:15500/health/replication
# Check replication status on replica
curl http://localhost:15501/health/replication
```
#### Consistency Guarantees
- **Master Reads**: Strongly consistent (immediate)
- **Replica Reads**: Eventually consistent (~5-10ms lag typical)
- **Write Durability**: Writes confirmed after master commit
- **Replication**: Asynchronous to replicas
- **Lag Monitoring**: Real-time offset tracking
See [docs/specs/REPLICATION.md](docs/specs/REPLICATION.md) for complete replication documentation.

### 🚀 Quick Start
```bash
# Clone and build
git clone https://github.com/hivellm/synap.git
cd synap
cargo build --release
# Run tests (456+ passing)
cargo test
# Run server
./target/release/synap-server --config config.yml
# Server starts at http://0.0.0.0:15500
# Use CLI client
./target/release/synap-cli
synap> SET mykey "Hello World"
synap> GET mykey
# Or via HTTP API
curl -X POST http://localhost:15500/kv/set \
-H "Content-Type: application/json" \
-d '{"key": "test", "value": "hello", "ttl": 3600}'
curl http://localhost:15500/kv/get/test
# Returns: "hello" (plain value, not wrapped JSON)
# Or via MCP (Cursor/Claude Desktop)
# Just ask: "Get the value of key 'test' from Synap"
# MCP tool synap_kv_get will be called automatically
```
### 📨 Queue System Examples
```bash
# Create queue
curl -X POST http://localhost:15500/queue/jobs \
-H "Content-Type: application/json" \
-d '{"max_depth": 10000, "ack_deadline_secs": 30}'
# Publish message
curl -X POST http://localhost:15500/queue/jobs/publish \
-H "Content-Type: application/json" \
-d '{"payload": [72,101,108,108,111], "priority": 9, "max_retries": 3}'
# Consume message
curl http://localhost:15500/queue/jobs/consume/worker-1
# Acknowledge (ACK)
curl -X POST http://localhost:15500/queue/jobs/ack \
-H "Content-Type: application/json" \
-d '{"message_id": "xxx-xxx-xxx"}'
```
### 🔒 Authentication Examples
```bash
# Basic Auth (Redis-style)
curl -u admin:password http://localhost:15500/queue/private/stats
# API Key (Bearer Token)
curl -H "Authorization: Bearer sk_XXXXX..." http://localhost:15500/queue/list
# API Key (Query Parameter)
curl http://localhost:15500/queue/list?api_key=sk_XXXXX...
```
