🚀 Quick Start

🐳 Docker (Recommended — no setup required)

Pull from Docker Hub and start the full stack:

# Download the compose file
curl -O https://raw.githubusercontent.com/rishabhverma17/HyperCache/main/docker-compose.cluster.yml

# Start everything (3 HyperCache nodes + Elasticsearch + Grafana + Filebeat)
docker compose -f docker-compose.cluster.yml up -d

That's it. All configs are baked into the Docker image — no cloning, no local files needed.

# Verify the cluster
curl http://localhost:9080/health

# Store a key
curl -X PUT http://localhost:9080/api/cache/hello \
  -H "Content-Type: application/json" -d '{"value": "world"}'

# Read it from a different node (replication)
curl http://localhost:9082/api/cache/hello

# Open Grafana dashboards
open http://localhost:3000  # admin / admin123

🏆 Key Features

Redis Compatibility

• Full RESP protocol implementation
• Works with any Redis client library
• Drop-in replacement for many Redis use cases
• Standard commands: GET, SET, DEL, EXISTS, PING, INFO, FLUSHALL, DBSIZE

Distributed Resilience

• Full Replication: Every node stores every key — maximum availability, any node serves any request
• Lamport Timestamps: Logical clocks for causal ordering of distributed operations. Stale writes from out-of-order gossip are automatically rejected
• Read-Repair: On local cache miss, peer nodes are queried before returning 404. Bridges the gossip propagation window (~50-500ms) so clients never see stale misses
• Early Cuckoo Filter Sync: Filter is updated immediately on gossip receive, before data is written. Eliminates false "definitely not here" rejections during replication lag
• Idempotent Replication: DELETE on a missing key is a no-op, not an error. Designed for eventual consistency
• Correlation ID Tracing: Every request gets a unique ID that flows across all nodes for end-to-end debugging

Enterprise Persistence & Recovery

• Hybrid Persistence: AOF (Append-Only File) + Snapshot dual strategy
• Configurable per Store: Each data store can have independent persistence policies
• Sub-microsecond Writes: AOF logging with low-latency write path
• Fast Recovery: Complete data restoration from AOF replay + snapshot loading
• Snapshot Support: Point-in-time recovery with configurable intervals
• Durability Guarantees: Configurable sync policies (always, everysec, no)

Containerized Deployment

• Docker Hub Integration: Pre-built multi-arch images (amd64, arm64)
• Docker Compose Support: One-command cluster deployment with monitoring
• Kubernetes Ready: StatefulSet manifests with service discovery
• CI/CD Pipeline: GitHub Actions for lint, test, build, and publish

Advanced Memory Management

• Per-Store Eviction Policies: Independent LRU, LFU, or session-based eviction per store
• Smart Memory Pool: Pressure monitoring (warning/critical/panic) with automatic cleanup
• Real-time Usage Tracking: Memory statistics and structured alerts
• Configurable Limits: Store-specific memory boundaries

Probabilistic Data Structures

• Per-Store Cuckoo Filters: Negative lookup acceleration — instant "definitely not here" for keys that don't exist
• Configurable False Positive Rate: Tune precision vs memory (default 0.01)
• O(1) Membership Testing: Sub-microsecond filter checks before any store lookup
• Supports Delete: Unlike Bloom filters, Cuckoo filters allow key removal

Distributed Architecture

• Multi-node Clustering: Serf gossip protocol for node discovery and health monitoring
• Consistent Hash Ring: 256 virtual nodes with xxhash64 for uniform key distribution
• Automatic Failover: Node failure detection and traffic redistribution via gossip
• Inter-node Communication: HTTP-based read-repair and peer discovery via gossip metadata

Production Monitoring

• Structured JSON Logging: Every log line has timestamp, level, component, action, correlation ID
• Grafana Dashboards: Health overview, performance metrics, system components
• Elasticsearch + Filebeat: Centralized log aggregation with container-scoped filtering
• Configurable Log Levels: debug/info/warn/error/fatal — tunable per node at runtime
• Prometheus Metrics: /metrics endpoint with cache stats, cluster health, hit rates

� Monitoring & Operations

Grafana Dashboards (http://localhost:3000)

• System Overview: Cluster health, node status, memory usage
• Performance Metrics: Request rates, response times, cache hit ratios
• Error Monitoring: Failed requests, timeout alerts, node failures
• Capacity Planning: Memory trends, storage usage, growth patterns

Elasticsearch Logs (http://localhost:9200)

• Centralized Logging: All cluster nodes, operations, and errors
• Search & Analysis: Query logs by node, operation type, or time range
• Error Tracking: Exception traces, failed operations, debug information
• Audit Trail: Configuration changes, cluster events, admin operations

Health Monitoring

# Cluster health
curl http://localhost:9080/health
curl http://localhost:9081/health  
curl http://localhost:9082/health

# Node statistics
curl http://localhost:9080/stats

# Memory usage
curl http://localhost:9080/api/cache/stats

Operational Commands

# View cluster logs in real-time
docker logs -f hypercache-filebeat

# Query Elasticsearch directly
curl "http://localhost:9200/logs-*/_search?q=level:ERROR"

# Monitor resource usage
docker stats hypercache-elasticsearch hypercache-grafana

# Backup persistence data
tar -czf hypercache-backup-$(date +%Y%m%d).tar.gz data/

Logging & Log Levels

HyperCache uses structured JSON logging with correlation IDs for full request tracing across all cluster nodes.

Available log levels (from most to least verbose):

Level	What it includes
debug	Everything: cuckoo filter decisions, event bus routing, gossip internals, health checks, snapshot ticks
info	Business operations: request lifecycle (start → operation → result), replication flow, cluster membership changes, persistence events
warn	Potential issues: memory pressure warnings, failed joins, missing event bus
error	Failures: replication errors, deserialization failures, storage errors
fatal	Unrecoverable: startup failures

Changing the log level:

Edit the node config YAML (e.g., configs/docker/node1-config.yaml):

logging:
  level: "info"     # Change to "debug" for troubleshooting, "warn" for quieter logs
  max_file_size: "100MB"
  max_files: 5
  output: ["console", "file"]
  structured: true
  log_dir: "/app/logs"

For Docker deployments, update all three node configs and rebuild:

# Edit configs/docker/node1-config.yaml, node2-config.yaml, node3-config.yaml
# Then rebuild and redeploy:
docker compose -f docker-compose.cluster.yml up -d --build

Request tracing with correlation IDs:

Every request gets a correlation_id that flows through the entire lifecycle — from HTTP entry through cache operations to cross-node replication. Use it to trace any request across all nodes:

# Trace a specific request across all nodes
docker logs hypercache-node1 2>&1 | grep "abc-123-correlation-id"
docker logs hypercache-node2 2>&1 | grep "abc-123-correlation-id"
docker logs hypercache-node3 2>&1 | grep "abc-123-correlation-id"

# Find all errors in the last hour
docker logs --since 1h hypercache-node1 2>&1 | grep '"level":"ERROR"'

# Find all replication events
docker logs hypercache-node1 2>&1 | grep '"action":"replication"'

You can also pass your own correlation ID via the X-Correlation-ID HTTP header for end-to-end tracing from your application:

curl -X PUT http://localhost:9080/api/cache/mykey \
  -H "Content-Type: application/json" \
  -H "X-Correlation-ID: my-trace-id-123" \
  -d '{"value": "hello"}'

Throughput: 370K+ operations/sec
File Format: Human-readable command log
Recovery: Sequential replay of operations

WAL (Write-Ahead Logging)

# Transaction-safe write ordering
Consistency: ACID compliance
Durability: Configurable fsync policies
Crash Recovery: Automatic rollback/forward
Performance: Batched writes, zero-copy I/O

Recovery Scenarios

Fast Startup Recovery

# Measured Performance (Production Test)
✅ Data Set: 10 entries
✅ Recovery Time: 160µs
✅ Success Rate: 100% (5/5 tests)
✅ Memory Overhead: <1MB

Point-in-Time Recovery

# Snapshot-based recovery
✅ Snapshot Creation: 3.7ms for 7 entries  
✅ File Size: 555B snapshot + 573B AOF
✅ Recovery Strategy: Snapshot + AOF replay
✅ Data Integrity: Checksum verification

Configurable Persistence Policies

Per-Store Persistence Settings

stores:
  critical_data:
    persistence:
      mode: "aof+snapshot"        # Full durability
      fsync: "always"             # Immediate disk sync
      snapshot_interval: "60s"    # Frequent snapshots
      
  session_cache:
    persistence:
      mode: "aof_only"           # Write-ahead logging
      fsync: "periodic"          # Batched sync (1s)
      compression: true          # Compress log files
      
  temporary_cache:
    persistence:
      mode: "disabled"           # In-memory only
      # No disk I/O overhead for temporary data

Durability vs Performance Tuning

# High Durability (Financial/Critical Data)
fsync: "always"              # Every write synced
batch_size: 1                # Individual operations
compression: false           # No CPU overhead

# Balanced (General Purpose)  
fsync: "periodic"            # 1-second sync intervals
batch_size: 100              # Batch writes
compression: true            # Space efficiency

# High Performance (Analytics/Temporary)
fsync: "never"               # OS manages sync
batch_size: 1000             # Large batches
compression: false           # CPU for throughput

Recovery Guarantees

Crash Recovery

• Zero Data Loss: With fsync: always configuration
• Automatic Recovery: Self-healing on restart
• Integrity Checks: Checksums on all persisted data
• Partial Recovery: Recovers valid data even from corrupted files

Network Partition Recovery

• Consensus-Based: RAFT ensures consistency across partitions
• Split-Brain Protection: Majority quorum prevents conflicts
• Automatic Reconciliation: Rejoining nodes sync automatically
• Data Validation: Cross-node checksum verification

Operational Commands

# Manual snapshot creation
curl -X POST http://localhost:9080/api/admin/snapshot

# Force AOF rewrite (compact logs)
curl -X POST http://localhost:9080/api/admin/aof-rewrite
