ABSTRACT:
A method and system for synchronization-replication concurrency maintain a history table for a data table in a mirror, where the history table can include redundant version values that indicate a period in which data values corresponding to the version values are valid. Replication can thus be performed between a source and a mirror for a current version of the data table, while synchronization is simultaneously performed between the mirror and a client for an earlier version of the data table using the history table.
