Accordingly, an optimistic data consistency maintenance method based on key-attributes is proposed. In the method, the update of key-attributes is separated from user update requests. Key-Updates are propagated by latency-overlay update propagation model, that is, updates are always propagated to the nodes having maximum or minimum latency, and assured and uncertain propagation paths of updates are all taken into account. Based on classifying key-update conflicts, a double-level reconciling mechanism including buffer preprocessing and update-log processing is applied to detect and reconcile conflicts, and then conflicts are solved by policies as last-writer-win and divide-and-rule. Lastly, update-log management method and maintenance method brought by node failure and network partitioning are discussed for the above is deployed based on the information storied in update-log.

在该方法中，首先分离出用户提交的更新请求中关于关键属性的更新；然后采用基于延迟-覆盖的更新传播模型进行更新传播，即基于副本间的网络延迟选择具有最大和最小网络延迟的结点转发更新，并在传播过程中记录和综合考虑更新的确定传播和不确定传播两条路径；在对关键更新冲突分类的基础上，采用更新缓冲区和更新日志两层更新协商机制并结合最新写胜出和分而治之规则，优化关键更新冲突的发现和解决；更新日志信息是方法中各种策略开展的基础，讨论了更新日志中信息管理方法以及结点失效和网络划分发生时信息的维护方法。

The ORF of profilin of Caryota mitis pollen was amplified by RT-PCR using specific primers and cloned into the expression vector pET-28a. The recombinant Caryota mitis pollen profilin was expressed in Escherichia coli BL21 (DE3). The recombinant protein was purified by affinity chromatography using Ni(superscript 2+) coupled sepharose.
