摘要： Disclosed herein are a system, method and architecture for optimizing a manner in which queries and updates are issued to data stores servicing an application such as a social networking application. A social graph modeling a social network may be used to generate a data store request schedule that optimizes, e.g., minimizes, data store accesses, such as without limitation queries and updates to the data store.

摘要： A method of caching posting lists to a search engine cache calculates the ratios between the frequencies of the query terms in a past query log and the sizes of the posting lists for each term, and uses these ratios to determine which posting lists should be cached by sorting the ratios in decreasing order and storing to the cache those posting lists corresponding to the highest ratio values. Further, a method of finding an optimal allocation between two parts of a search engine cache evaluates a past query stream based on a relationship between various properties of the stream and the total size of the cache, and uses this information to determine the respective sizes of both parts of the cache.

摘要： A method and system for quantifying the quality of search results from a search engine based on cohesion. The method and system include modeling a set of search engine search results as a cluster and measuring the cohesion of the cluster. In an embodiment, the cohesion of the cluster is the average similarity between the cluster elements to a centroid vector. The centroid vector is the average of the weights of the vectors of the cluster. The similarity between the centroid vector and the cluster's elements is the cosine similarity measure. Each document in the set of search results is represented by a vector where each cell of the vector represents a stemmed word. Each cell has a cell value which is the frequency of the corresponding stemmed word in a document multiplied by a weight that takes into account the location of the stemmed word within the document.

摘要： Described is a reliable and efficient design for a transactional status oracle (“ReTSO”), which supports large-scale storage systems. ReTSO uses a centralized scheme and implements snapshot isolation, a property that guarantees that read operations read a consistent snapshot of the data store. The centralized scheme of ReTSO enables a lock-free commit algorithm that prevents unreleased locks of a failed transaction from blocking other transactions. Each transaction submits the identifiers of modified rows to the ReTSO, the transaction is committed only if none of the modified rows is committed by a concurrent transaction, and a log of the committed transaction is cached. To recover from failures, before a client is notified of a change, the change cached is first persisted into a write-ahead log, such that the memory state can be fully reconstructed by reading from the write-ahead log. Furthermore, ReTSO implements a lazy, auto-garbage collector hash map that reduces the number of memory accesses per request.
摘要翻译： 描述了一种支持大型存储系统的事务状态oracle（“ReTSO”）的可靠和高效的设计。 ReTSO使用集中式方案并实现快照隔离，这是一种保证读操作读取数据存储一致快照的属性。 ReTSO的集中式方案实现了一种无锁提交算法，可防止未发送的锁定失败的事务阻止其他事务。 每个事务将修改后的行的标识符提交给ReTSO，只有当并发事务不提交修改的行时，才会提交事务，并且缓存已提交的事务的日志。 要从故障中恢复，在客户端通知更改之前，缓存的更改将首先保存在预写日志中，以便可以通过从预读日志中读取来完全重建内存状态。 此外，ReTSO还实现了一种懒惰的自动垃圾收集器散列图，可以减少每个请求的内存访问次数。
