Abstract: A first transaction manager of a partitioned storage group stores a first conditional commit record for a first write of a multi-partition transaction based on a first conflict detection operation. A second transaction manager stores a second conditional commit record for a second write of the transaction based on a second conflict detection operation. A client-side component of the storage group determines that both writes have been conditionally committed, and stores an unconditional commit record in a commit decision repository. A write applier examines the first conditional commit record and the unconditional commit record before propagating the first write to the first partition.

Abstract translation: 分区存储组的第一事务管理器基于第一冲突检测操作存储用于多分区事务的第一写入的第一条件提交记录。 第二事务管理器基于第二冲突检测操作来存储用于事务的第二写入的第二条件提交记录。 存储组的客户端组件确定两个写入都已有条件地提交，并在提交决策存储库中存储无条件提交记录。 写入应用程序在将第一个写入传播到第一个分区之前检查第一个条件提交记录和无条件提交记录。
