摘要： Provided are techniques for, in response to a source object being changed by a local transaction, generating log records, wherein each of the log records includes a sequence identifier, a source system entity modification timestamp, a target key, a target partition identifier, and values of source properties, wherein the source properties are identified using a target key indicator. The log records to process are selected based on a phase value of each log record, wherein the phase value is one of submitted, in-flight, and source system entity state change complete. One or more disjoint partitions are assigned to each of multiple processing instances. Under control of each of the multiple processing instances, it is determined whether to transmit a log record in the one or more disjoint partitions assigned to said processing instance and, in response to determining that the log record is to be transmitted, the log record is transmitted.
