摘要： A method for verifying a consistency level in a key-value store, in which a value is stored in a cloud-based storage system comprising a read/write register identified by a key. At a centralized monitor node, a history of operations including writes and reads performed at the key is created, and a distance between a read of a value at the key and a latest write to the key is determined. It can then be ascertained whether the distance satisfies a relaxed atomicity property.

摘要： An embodiment provides a method for server replication and transaction commitment. The method includes receiving a transaction from a client node at one or more memory nodes, each memory node comprising a number of replicas, and determining, for each one of the replicas, whether the replica is able to commit the transaction. The method also includes sending a response from each of the replicas to a consensus node, wherein the consensus node is configured to record whether the response is a commit response. The method further includes committing the transaction if, at each memory node, a quorum of the replicas is able to commit the transaction, and aborting the transaction otherwise.

摘要： An embodiment provides a system and method for transaction commitment and replication. The method includes receiving a minitransaction from a client node at one or more memory nodes, wherein each memory node includes a number of replicas. The minitransaction is a type of transaction which atomically executes any combination of reading, comparing, and writing to any of a number of memory locations. The method also includes determining, for a leader of the replicas within a memory node, whether the leader is able to commit the minitransaction and stabilizing state changes of the minitransaction within a transaction log using a consensus procedure to update the replicas. The method further includes committing the minitransaction if, at each memory node, a quorum of the replicas is able to stabilize the minitransaction, or aborting the minitransaction otherwise.
摘要翻译： 一个实施例提供了用于事务承诺和复制的系统和方法。 该方法包括从一个或多个存储器节点处的客户端节点接收最小的转移，其中每个存储器节点包括多个副本。 minitransaction是一种事务，它以原子方式执行读取，比较和写入任意多个内存位置的任何组合。 该方法还包括针对内存节点内的副本的领导者，确定领导者是否能够使用协商一致的过程提交事务日志中的最小交易的最小交易和稳定状态变化来更新副本。 该方法还包括：在每个存储节点处，复制品的法定人数能够稳定最小化交易，或者中止其中的小交易。

摘要： A distributed balanced tree having a plurality of nodes distributed across a plurality of servers is accessed. Version information associated with a node of the distributed balanced tree is retrieved. Validity of a lookup transaction performed on the balanced tree is determined by verifying a version value of only the leaf node accessed during the lookup operation against the retrieved version information.
