    摘要： Provided are techniques for partitioning a physical index into one or more physical partitions; assigning each of the one or more physical partitions to a node in a cluster of nodes; for each received document, assigning an assigned-doc-ID comprising an integer document identifier; and, in response to assigning the assigned-doc-ID to a document, determining a cut-off of assignment of new documents to a current virtual-index-epoch comprising a first set of physical partitions and placing the new documents into a new virtual-index-epoch comprising a second set of physical partitions by inserting each new document to a specific one of the physical partitions in the second set using one or more functions that direct the placement based on one of the assigned-doc-id, a field value derived from a set of fields obtained from the document, and a combination of the assigned-doc-id and the field value.

    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.
