批量数据同步与外键约束

Batch data synchronization with foreign key constraints
Abstract:
Data in tables with foreign key relationship is synchronized in batches employing a two-pass process during playback based on whether the foreign key constraint is a linear dependency, self-referencing, or cyclic. A separate table containing a primary key of records and database timestamp columns for change operations may also be used for batch synchronization in addition to or instead of adding database timestamp columns to existing tables.
