Multiple source database system consolidation

摘要

A method, system, and program product for enabling multiple source database coherency is provided. The method includes detecting an incoming query to be executed with respect to an accelerator server. An initial timestamp of the incoming query is analyzed and additional timestamps of database tables referenced by the incoming query are retrieved. It is determined that each timestamp of the additional timestamps is reached with respect to a corresponding replication engine and target data from the database tables is synchronized with source data of a source database. In response, the incoming query is accelerated for execution with respect to a target database management system.
