分布式数据管理【分布式数据库同步时出现数据冲突，如何自定义合并策略？】】

// 冲突解决策略实现
class ConflictResolver {
  static customResolve(local: DataObject, remote: DataObject): DataObject {
    // 业务优先级判断
    if (local.priority > remote.priority) {
      return this.mergeWithPriority(local, remote);
    }

    // 时间戳比对
    const timeDiff = local.timestamp - remote.timestamp;
    if (Math.abs(timeDiff) > 5000) {
      return timeDiff > 0 ? local : remote;
    }

    // 数据完整性比较
    return local.integrityScore > remote.integrityScore ? local : remote;
  }

  private static mergeWithPriority(a: DataObject, b: DataObject): DataObject {
    // 深度合并算法实现
    return { ...a, ...b, version: Math.max(a.version, b.version) + 1 };
  }
