Configuration

No configuration changes required. The caching system uses sensible defaults:

// Default cache configuration (optional customization)
const config: CacheConfig = {
  maxEntries: 1000,      // Maximum cached records
  maxMemoryMB: 50,       // Memory limit per file
  enableMetrics: true    // Performance tracking
};

const loader = DB2CachedLoaderFactory.getLoader('Spell.db2', config);

💡 Usage Examples

Quick Start (5 Minutes)

import { DB2CachedLoaderFactory } from './parsers/db2/DB2CachedFileLoader';
import { SpellSchema } from './schemas/SpellSchema';

// 1. Get a cached loader
const spellLoader = DB2CachedLoaderFactory.getLoader('Spell.db2');

// 2. Load the DB2 file
spellLoader.loadFromFile('/path/to/Spell.db2');

// 3. Query a spell (cached automatically)
const spell = spellLoader.getTypedRecord<SpellEntry>(100);

console.log(`Spell: ${spell?.name}`);
console.log(`Range: ${spell?.maxRange} yards`);
console.log(`Cast Time: ${spell?.castTime}ms`);

// 4. Check cache performance
const stats = spellLoader.getCacheStats();
console.log(`Cache hit rate: ${(stats.totalHits / (stats.totalHits + stats.totalMisses) * 100).toFixed(1)}%`);

Bot Spell Lookup

class BotSpellManager {
  private spellLoader: DB2CachedFileLoader;

  constructor() {
    this.spellLoader = DB2CachedLoaderFactory.getLoader('Spell.db2');
    this.spellLoader.loadFromFile('/path/to/Spell.db2');

    // Warm cache with commonly used spells
    this.spellLoader.preloadRecords([100, 116, 133, 168, 203]);
  }

  canCastSpell(spellId: number, targetDistance: number): boolean {
    const spell = this.spellLoader.getTypedRecord<SpellEntry>(spellId);

    if (!spell) {
      console.warn(`Spell ${spellId} not found`);
      return false;
    }

    // Check range
    if (targetDistance > spell.maxRange) {
      return false;
    }

    // Check if instant cast or reasonable cast time
    return spell.castTime === 0 || spell.castTime < 3000;
  }

  getSpellCooldown(spellId: number): number {
    const spell = this.spellLoader.getTypedRecord<SpellEntry>(spellId);
    return spell?.cooldown ?? 0;
  }
}

Server Startup Optimization

import { CacheWarmer } from './tools/cachewarmer';

async function initializeMCPServer() {
  console.log('🚀 Starting TrinityCore MCP Server...\n');

  // Warm all critical caches at startup
  const result = await CacheWarmer.warmAllCaches();

  if (result.success) {
    console.log(`✅ Cache warming complete in ${result.totalTime}ms`);
    console.log(`   Files warmed: ${result.filesWarmed}`);
    console.log(`   Records cached: ${result.recordsCached}`);
    console.log(`   Memory used: ${result.memoryUsedMB.toFixed(2)}MB\n`);
  } else {
    console.error(`❌ Cache warming failed: ${result.error}`);
  }

  console.log('🎮 TrinityCore MCP Server ready!\n');
}

🔧 Breaking Changes

None

v1.4.0 is fully backward compatible with v1.3.0. All existing tools and APIs continue to work without modification.

Deprecations

No APIs have been deprecated in this release.

🐛 Known Issues & Limitations

Non-Blocking Issues

  1. Legacy Test Files (2 files)

    • SpellSchema.test.ts - Outdated field references
    • ItemSchema.test.ts - Outdated mock objects
    • Status: Non-blocking (SchemaSmoke.test.ts provides coverage)
    • Priority: LOW (maintenance sprint)
    • Workaround: Use SchemaSmoke tests for validation

  2. Jest Configuration Warning

    • ts-jest global config deprecation warning
    • Impact: None (warning only, does not affect functionality)
    • Priority: LOW

Architectural Limitations

  1. Single-threaded caching (Node.js limitation)

    • Not a limitation for most use cases (10,000+ queries/second)

  2. In-memory only (no persistent cache)

    • Design choice for maximum performance
    • Consider Redis integration for future phases

  3. No compression (intentional for speed)

    • Prioritizes access speed over storage
    • Memory usage remains within targets

  4. Size estimation (approximate, not exact)

    • Uses conservative estimates
    • Actual memory usage may be lower
