Quick Start with Docker

# 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):

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):

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:

# 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:

# 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):

# 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:

# 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 for complete replication documentation.
