Architecture

WarpEngine uses creative terminology for standard database optimization techniques:

"Quantum Entanglement" (Intelligent Prefetching)

Automatically learns which data items are frequently accessed together and prefetches related data in parallel:

# When you access a user, related profile and settings are automatically prefetched
{:ok, user, quantum_data} = WarpEngine.quantum_get("user:alice")
# quantum_data contains prefetched profile:alice, settings:alice, etc.

"Gravitational Routing" (Locality-Aware Sharding)

Data placement algorithm that considers access patterns and data relationships:

# Hot, frequently-accessed data goes to high-performance shards
WarpEngine.cosmic_put("trending:post:123", post_data, access_pattern: :hot)

# Cold, archived data goes to compressed storage shards  
WarpEngine.cosmic_put("archive:2020:data", old_data, access_pattern: :cold)

"Event Horizon Cache" (Multi-Level Caching)

Hierarchical caching system with intelligent eviction:

"Entropy Monitoring" (Statistical Load Balancing)

Uses Shannon entropy calculations to detect load imbalances and trigger automatic rebalancing.

Quick Start

Installation

Add to your mix.exs:

def deps do
  [
    {:warp_engine, "~> 1.0"},
    {:jason, "~> 1.4"}
  ]
end

Basic Usage

# Start WarpEngine
{:ok, _pid} = WarpEngine.start_link()

# Store data with automatic optimization
{:ok, :stored, shard, time} = WarpEngine.cosmic_put("user:alice", %{
  name: "Alice Johnson", 
  email: "alice@example.com"
})

# Retrieve data with potential prefetching
{:ok, user_data, shard, time} = WarpEngine.cosmic_get("user:alice")

# Get performance metrics
metrics = WarpEngine.cosmic_metrics()

Advanced Operations

# Intelligent prefetching with quantum entanglement
{:ok, response} = WarpEngine.quantum_get("user:alice")
# Automatically prefetches related data based on learned patterns

# Create custom entanglement relationships  
WarpEngine.create_quantum_entanglement("user:alice", 
  ["profile:alice", "settings:alice"], 0.9)

# Monitor system performance and entropy
metrics = WarpEngine.cosmic_metrics()
entropy = WarpEngine.entropy_metrics()

# Manually trigger system optimization
WarpEngine.trigger_entropy_rebalancing(force_rebalancing: true)

Configuration

  # Data storage location
  data_root: "/path/to/data",
  
  # Enable optimizations

  enable_gravitational_routing: true,   # Locality-aware sharding
  enable_event_horizon_cache: true,     # Multi-level caching
  enable_entropy_monitoring: true,      # Load balancing
  
  # Prefetch patterns
  entanglement_rules: [
    {"user:*", ["profile:*", "settings:*"]},
    {"order:*", ["customer:*", "products:*"]},

Graph Database Example

While WarpEngine core is a key-value database, a graph database example is available that demonstrates how to build graph operations on top of WarpEngine:

# Explore the graph database implementation built on WarpEngine
mix run examples/weighted_graph_database.ex

The example provides graph operations like store_node/1, store_edge/1, traverse_graph/3, and generate_recommendations/2.

Benchmarking

Run performance tests:

# Basic performance
mix run simple_benchmark.exs

# Multi-core scaling
mix run multi_core_benchmark.exs

# Graph database comparison (uses the example implementation)
mix run benchmarks/simple_weighted_graph_benchmark.exs

Testing

mix test                    # Run all 175+ tests
mix test --max-cases 1      # Run tests sequentially

About

WarpEngine represents a creative approach to database optimization, using physics-inspired metaphors for well-known techniques like intelligent caching, locality-aware sharding, and statistical load balancing. While the terminology is unconventional, the underlying optimizations are sound and provide measurable performance benefits.

Built with Elixir/OTP for reliability and performance on the Erlang VM.

Note: The physics metaphors ("quantum entanglement", "gravitational routing", etc.) are creative terminology for standard database optimization techniques. They don't involve actual physics but represent innovative approaches to data placement, caching, and load balancing.
