重新设计的BaBar活动商店：相信炒作
The Redesigned BaBar Event Store: Believe the Hype
摘要：
随着BaBar实验的进展，它产生了新的和不可预见的需求，并对容量和特征库提出了越来越高的要求。目前系统的使用远远超出了其最初的设计规格，并已适当扩展，保持了数据的一致性和耐用性。持久事件存储系统自最初实现以来基本保持不变，因此包括许多已成为性能瓶颈的设计特征。编程接口是在有足够的使用信息可用之前设计的。性能和效率得到了权衡，以增加灵活性，以应对未来的需求。凭借我们在管理实际生产数据方面的丰富经验，我们现在能够重新设计系统，以更好地满足当前的需求。事件存储重新设计旨在消除冗余功能，同时添加新功能，提高整体性能，并控制世界上最大数据库的物理存储成本。
英文摘要：
As the BaBar experiment progresses, it produces new and unforeseen requirements and increasing demands on capacity and feature base. The current system is being utilized well beyond its original design specifications, and has scaled appropriately, maintaining data consistency and durability. The persistent event storage system has remained largely unchanged since the initial implementation, and thus includes many design features which have become performance bottlenecks. Programming interfaces were designed before sufficient usage information became available. Performance and efficiency were traded off for added flexibility to cope with future demands. With significant experience in managing actual production data under our belt, we are now in a position to recraft the system to better suit current needs. The Event Store redesign is intended to eliminate redundant features while adding new ones, increase overall performance, and contain the physical storage cost of the world's largest database.
