用于启用事件删除的分布式数据库的方法和设备
摘要：
在一些实施例中，一种设备包括与被配置为包括在第一组计算装置内的计算装置处的分布式数据库的实例相关联的存储器。所述设备被配置为基于事件共识协议的不同配置来确定事件集合中的每个事件的次序。所述不同配置在逻辑上与实现分布式数据库的计算装置的不同配置是相关的。所述设备被配置为基于对事件集合中的每个事件确定的次序来确定分布式数据库的实例的当前状态，并且基于与当前状态相关联的散列值来产生与分布式数据库的实例相关联的带签名状态。所述设备发送将包括指示带签名状态的事务的事件发布到分布式数据库的实例中的信号。
摘要（英）：

In some embodiments, an apparatus includes a memory associated with an instance of a distributed database at a compute device configured to be included within a first group of compute devices. The apparatus is configured to determine an order for each event from the set of events based on different configurations of an event consensus protocol. The different configurations are logically related todifferent configurations of compute devices that implement the distributed database. The apparatus is configured to determine a current state of the instance of the distributed database based on theorder determined for each event from the set of events and generate a signed state associated with the instance of the distributed database based on a hash value associated with the current state. Theapparatus sends a signal to post into the instance of the distributed database an event that includes a transaction indicative of the signed state.
