18## Quick Start
19
20### Installation
21
22```bash
23git clone https://github.com/your-org/gigabrain.git
24cd gigabrain
25cargo build --release
26```
27
28### Running the Server
29
30```bash
31# Start both REST (port 3000) and gRPC (port 50051) servers
32cargo run --bin gigabrain
33```
34
35### Using the CLI
36
37```bash
38# Build and start the interactive CLI
39cargo build --release --bin gigabrain-cli
40./target/release/gigabrain-cli
41
42# Execute a single command
43./target/release/gigabrain-cli --execute "CREATE (alice:Person {name: 'Alice', age: 30})"
44
45# Run commands from file
46./target/release/gigabrain-cli --file my_queries.cypher
47
48# Show graph statistics
49./target/release/gigabrain-cli stats
50```
51
52### Basic Usage
53
54#### Using the CLI (Recommended)
55
56```cypher
57# Start interactive CLI
58gigabrain> CREATE (alice:Person {name: 'Alice', age: 30})
59gigabrain> CREATE (bob:Person {name: 'Bob', age: 25})
60gigabrain> MATCH (a:Person), (b:Person) WHERE a.name = 'Alice' AND b.name = 'Bob'
61 -> CREATE (a)-[:KNOWS]->(b)
62gigabrain> MATCH (p:Person)-[:KNOWS]->(friend) RETURN p.name, friend.name
63```
64
65#### Using the REST API
66
67```bash
68# Check server health
69curl http://localhost:3000/api/v1/health
70
71# Create a node
72curl -X POST http://localhost:3000/api/v1/nodes \
73 -H "Content-Type: application/json" \
74 -d '{
75 "labels": ["Person"],
76 "properties": [
77 {"key": "name", "value": {"string_value": "Alice"}},
78 {"key": "age", "value": {"int_value": 30}}
79 ]
80 }'
81
82# Execute a Cypher query
83curl -X POST http://localhost:3000/api/v1/cypher \
84 -H "Content-Type: application/json" \
85 -d '{
86 "query": "MATCH (n:Person) RETURN n.name, n.age"
87 }'

303```
304
305### Production Considerations
306
307- **High Availability**: Deploy multiple instances with load balancing
308- **Backup Strategy**: Regular snapshots for persistent storage
309- **Monitoring**: Use Prometheus metrics and distributed tracing
310- **Security**: Enable TLS, rotate JWT secrets regularly
311- **Resource Limits**: Configure memory and CPU limits appropriately
312
313## Monitoring and Observability
314
315### Metrics
316
317GigaBrain exposes Prometheus-compatible metrics:
318
319```
320# Node and relationship counts
321gigabrain_nodes_total
322gigabrain_relationships_total
323
324# Query performance
325gigabrain_query_duration_seconds
326gigabrain_query_errors_total
327
328# API performance
329gigabrain_http_requests_total
330gigabrain_grpc_requests_total
331
332# System resources
333gigabrain_memory_usage_bytes
334gigabrain_cpu_usage_percent
335```
336
337### Logging
338
339Structured logging with multiple levels:
340
341```rust
342use tracing::{info, warn, error};
343
344info!(node_id = %node.id, "Node created successfully");
345warn!(query = %cypher, duration_ms = %elapsed, "Slow query detected");
346error!(error = %e, "Failed to process request");
347```
348
349### Tracing
350
351Distributed tracing support with OpenTelemetry:
352
353```rust
354use tracing_opentelemetry::OpenTelemetryLayer;
355
356// Configure tracing
357let tracer = opentelemetry_jaeger::new_pipeline()
358 .with_service_name("gigabrain")
359 .install_simple()?;
360```
