Abstract
A method comprises receiving a stream of change log records from a source database system; generating change statistics based on a number of pending changes per table partition according to the change log records; estimating, based on performance statistics, a first amount of time for applying the pending changes to a target database system using an incremental update path; estimating, based on the performance statistics, a second amount of time for applying the pending changes to the target database using a bulk update path; dynamically selecting, based on comparison of the first amount of time with the second amount of time, one of the incremental update path and the bulk update path for applying the pending changes to the target database system; and applying the pending changes to the target database system using the selected update path.
