Abstract: A sequence of configuration-delta messages from a configuration manager of a replication graph established for replicating state information of an application is received at a particular node of the graph. Representations of the messages are stored in a local configuration change repository. Using the repository, the node identifies neighbor source nodes and destination nodes of the graph. Subsequent to receiving a particular configuration-delta message indicating that a neighbor source node has been removed from the graph, a different source node is identified by the particular node, and a request is sent to the different source node to transmit a set of state transition messages pertaining to the application.

Abstract: At a logging service, a representation of a transaction requested by a client is received. The transaction includes at least a first write operation directed to a data object at a first data store. Based at least in part on the contents of the representation and contents of a persistent log of the logging service, a determination is made that the requested transaction is to be committed. A log record corresponding to the first write operation is inserted into the persistent log. The first write is propagated to the first data store after the record has been inserted in the persistent log.

Abstract translation: 在记录服务中，接收到客户端请求的交易的表示。 交易包括在第一数据存储处至少针对数据对象的第一写入操作。 至少部分地基于日志服务的持久日志的表示和内容的内容，确定要请求的事务被提交。 对应于第一次写入操作的日志记录被插入到永久日志中。 在将记录插入永久日志之后，第一个写入将传播到第一个数据存储。

Abstract: A transaction request is received at a log-based transaction manager, indicating a conflict check delimiter and a read set descriptor indicative of one or more locations from which data is read during the requested transaction. Using the conflict check delimiter, a subset of transaction records stored in a particular persistent log to be examined for conflicts prior to committing the requested transaction is identified. In response to determining that none of the read locations of the requested transaction correspond to a write location indicated in the subset of transaction records, a new transaction record is stored in the particular persistent log indicating that the requested transaction has been committed.

Abstract translation: 在基于日志的事务管理器处接收到交易请求，指示冲突检查分隔符和指示在所请求的交易期间从其读取数据的一个或多个位置的读取集描述符。 使用冲突检查分隔符，识别存储在特定持久日志中的事务记录的子集，以在提交所请求的事务之前检查冲突。 响应于确定所请求的交易的读取位置中没有一个对应于在事务记录的子集中指示的写入位置，新的事务记录被存储在特定持久日志中，指示所请求的交易已被提交。
