/**
 * Ductape Warehouse
 *
 * Unified data warehouse interface for cross-database operations
 * across traditional databases, graphs, and vector stores.
 *
 * @example
 * // Initialize warehouse
 * const warehouse = new WarehouseService(
 *   databaseService,
 *   graphService,
 *   vectorService,
 *   { env: 'production', product: 'myapp' }
 * );
 *
 * // Register data sources
 * await warehouse.registerDatabase('users-postgres');
 * await warehouse.registerGraph('social-neo4j');
 * await warehouse.registerVector('embeddings-pinecone');
 *
 * // Cross-database query
 * const result = await warehouse.query({
 *   operation: 'select',
 *   from: { type: 'database', tag: 'users-postgres', entity: 'users', alias: 'u' },
 *   fields: ['u.name', 'u.email', 'friends.name as friend_name'],
 *   join: [
 *     {
 *       type: 'left',
 *       source: { type: 'graph', tag: 'social-neo4j', entity: 'Person', alias: 'friends' },
 *       graph: { relationship: 'FRIENDS_WITH', direction: 'both' },
 *       on: { left: 'u.id', right: 'friends.userId' }
 *     }
 *   ],
 *   where: { 'u.status': { $eq: 'active' } },
 *   limit: 100
 * });
 *
 * // Semantic search with database enrichment
 * const similar = await warehouse.query({
 *   operation: 'select',
 *   from: { type: 'vector', tag: 'embeddings-pinecone', entity: 'documents', alias: 'v' },
 *   fields: ['v.id', 'v.score', 'doc.title', 'doc.content'],
 *   join: [
 *     {
 *       type: 'inner',
 *       source: { type: 'database', tag: 'docs-postgres', entity: 'documents', alias: 'doc' },
 *       on: { left: 'v.id', right: 'doc.id' }
 *     }
 *   ],
 *   where: {
 *     'v': { $similar: { vector: queryEmbedding, threshold: 0.8, topK: 10 } }
 *   }
 * });
 *
 * // Cross-database transaction
 * const txResult = await warehouse.transaction([
 *   {
 *     operation: 'insert',
 *     from: { type: 'database', tag: 'orders-postgres', entity: 'orders' },
 *     data: { userId: 'u1', total: 99.99 }
 *   },
 *   {
 *     operation: 'insert',
 *     from: { type: 'graph', tag: 'activity-neo4j', entity: 'Event' },
 *     data: { type: 'ORDER_PLACED', userId: 'u1' }
 *   },
 *   {
 *     operation: 'upsert',
 *     from: { type: 'vector', tag: 'user-behavior-pinecone', entity: 'behaviors' },
 *     data: { id: 'u1_order', vector: [...], metadata: { action: 'order' } }
 *   }
 * ]);
