Deployment Topologies

Topology 1: Minimal Development Setup

Use Case: Local development and testing

Components:

  • 1 PD node (fake-pd mode or real PD)
  • 1 Store node
  • 1 Server node (optional)

Configuration:

Store Node (with fake-pd):

pdserver:
  address: localhost:8686

grpc:
  host: 127.0.0.1
  port: 8500

raft:
  address: 127.0.0.1:8510

app:
  data-path: ./storage
  fake-pd: true  # Built-in PD mode

Characteristics:

  • ✅ Simple setup, fast startup
  • ✅ No external PD cluster required
  • ❌ No high availability
  • ❌ No data replication
  • ❌ Not for production

Topology 2: Small Production Cluster

Use Case: Small production deployments, testing environments

Components:

  • 3 PD nodes
  • 3 Store nodes
  • 2-3 Server nodes

Architecture:

IP Allocation Example:

  • PD: 192.168.1.10-12
  • Store: 192.168.1.20-22
  • Server: 192.168.1.30-32

Partition Configuration (in PD):

partition:
  default-shard-count: 3     # 3 replicas per partition
  store-max-shard-count: 12  # Max 12 partitions per Store

Capacity:

  • Data size: Up to 1TB (with proper disk)
  • QPS: ~5,000-10,000 queries/second
  • Availability: Tolerates 1 node failure per component

Characteristics:

  • ✅ High availability (HA)
  • ✅ Data replication (3 replicas)
  • ✅ Automatic failover
  • ✅ Production-ready
  • ⚠️ Limited horizontal scalability

Topology 3: Medium Production Cluster

Use Case: Medium-scale production deployments

Components:

  • 3 PD nodes
  • 6-9 Store nodes
  • 3-6 Server nodes

Architecture:

Store1   Store2   Store3   Store4   Store5   Store6
  (Rack 1)  (Rack 1) (Rack 2) (Rack 2) (Rack 3) (Rack 3)

Rack-Aware Placement (configured in PD):

  • Distribute replicas across racks for fault isolation
  • Each partition has replicas on different racks

Partition Configuration:

partition:
  default-shard-count: 3        # 3 replicas
  store-max-shard-count: 20     # More partitions per Store

Capacity:

  • Data size: 5-10TB
  • QPS: ~20,000-50,000 queries/second
  • Availability: Tolerates rack-level failures

Characteristics:

  • ✅ High availability with rack isolation
  • ✅ Better horizontal scalability
  • ✅ Higher throughput
  • ⚠️ More complex deployment

Topology 4: Large-Scale Cluster

Use Case: Large-scale production deployments with high throughput

Components:

  • 5 PD nodes
  • 12+ Store nodes
  • 6+ Server nodes

Architecture:

         Load Balancer Layer

  Store Pool (Zone A)  Store Pool (Zone B)
  6-12 nodes           6-12 nodes

Multi-Zone Deployment:

  • PD: 5 nodes across 2-3 availability zones
  • Store: Distributed across zones with zone-aware replica placement
  • Server: Load-balanced across zones

Partition Configuration:

partition:
  default-shard-count: 3
  store-max-shard-count: 30-50  # High partition count for load distribution

Capacity:

  • Data size: 20TB+
  • QPS: 100,000+ queries/second
  • Availability: Tolerates zone-level failures

Characteristics:

  • ✅ Maximum availability and scalability
  • ✅ Zone-level fault tolerance
  • ✅ Elastic scaling
  • ⚠️ Complex operational overhead

Topology 5: Co-located Deployment

Use Case: Resource optimization, smaller deployments

Components:

  • 3 nodes, each running: PD + Store + Server

Architecture:

Node 1 (192.168.1.10)          Node 2 (192.168.1.11)          Node 3 (192.168.1.12)

Port Allocation (per node):

  • Server: 8080 (REST), 8182 (Gremlin)
  • PD: 8686 (gRPC), 8620 (REST), 8610 (Raft)
  • Store: 8500 (gRPC), 8520 (REST), 8510 (Raft)

Characteristics:

  • ✅ Lower hardware cost (fewer machines)
  • ✅ Simplified networking
  • ⚠️ Resource contention between components
  • ⚠️ Lower fault isolation (node failure affects all components)

Recommendations:

  • Use for small to medium workloads
  • Ensure sufficient CPU (16+ cores) and memory (64GB+) per node
  • Use separate disks for Store data and PD metadata

Deployment Steps

Step 1: Prerequisites

On all nodes:

# Check Java version (11+ required)
java -version

# Check Maven (for building from source)
mvn -version

# Check network connectivity
ping 192.168.1.10
ping 192.168.1.11

# Check available disk space
df -h

# Open required ports (firewall)
# PD: 8620, 8686, 8610
# Store: 8500, 8510, 8520
# Server: 8080, 8182

Disk Recommendations:

  • PD: 50GB+ (for metadata and Raft logs)
  • Store: 500GB+ per node (depends on data size)
  • Server: 20GB (for logs and temp data)

Step 2: Deploy PD Cluster

On each PD node:

# Extract PD distribution
tar -xzf apache-hugegraph-pd-incubating-1.7.0.tar.gz
cd apache-hugegraph-pd-incubating-1.7.0

# Edit configuration
vi conf/application.yml
# Update grpc.host, raft.address, raft.peers-list

Deploy:

# Create namespace
kubectl create namespace hugegraph

# Deploy PD cluster (prerequisite)
kubectl apply -f hugegraph-pd-statefulset.yaml -n hugegraph

# Deploy Store cluster
kubectl apply -f hugegraph-store-statefulset.yaml -n hugegraph

# Check pods
kubectl get pods -n hugegraph

# Check Store logs
kubectl logs -f hugegraph-store-0 -n hugegraph

# Access Store service
kubectl port-forward svc/hugegraph-store 8500:8500 -n hugegraph

Verification and Testing

Health Check

# PD health
curl http://192.168.1.10:8620/v1/health

# Store health
curl http://192.168.1.20:8520/v1/health

Cluster Status

# PD cluster members
curl http://192.168.1.10:8620/v1/members

# Registered stores
curl http://192.168.1.10:8620/v1/stores

# Partitions
curl http://192.168.1.10:8620/v1/partitions

# Graph list

Basic Operations Test

# Create vertex via Server
curl -X POST "http://192.168.1.30:8080/graphspaces/{graphspace_name}/graphs/{graph_name}/graph/vertices" \
     -H "Content-Type: application/json" \
     -d '{
         "label": "person",
         "properties": {
             "name": "marko",
             "age": 29
         }
     }'

# Query vertex (using -u if auth is enabled)
curl -u admin:admin \
     -X GET "http://localhost:8080/graphspaces/{graphspace_name}/graphs/graphspace_name}/graph/vertices/{graph_id}

Performance Baseline Test

# Install HugeGraph-Loader (for bulk loading)
tar -xzf apache-hugegraph-loader-1.7.0.tar.gz

# Run benchmark
bin/hugegraph-loader.sh -g hugegraph -f ./example/struct.json -s ./example/schema.groovy
