Abstract
A computer-implemented method includes, by a streaming analytics component, identifying a source database table and a target database table. The target database table includes one or more target database rows and one or more target database columns. The method further includes identifying a change stream including a plurality of row-level modifications that cause the target database table to replicate the source database table. The method further includes determining that each row-level modification affects one or more common columns of the target database columns, wherein the common columns exhibit one or more common values for those of the target database rows that are affected by the row-level modifications. The method further includes generating, based on the common values and the common columns, a reconstructed modification statement and sending the reconstructed modification statement to an apply component. A corresponding computer program product and computer system are also disclosed.
