Abstract
Official abstract text for this publication.
Disclosed herein are system, method, and computer program product embodiments for exporting and importing database tables in a database management system using multi-version concurrency control (MVCC). An embodiment operates by first initiating an export of a database table in the database management system. During the export transaction, temporary creation and deletion timestamps are identified from MVCC information associated with each row in the database table. Each temporary timestamp is associated with a database transaction. A timestamp map is then generated that associates the identified temporary timestamps with commit timestamps of the associated transactions. The database table, associated MVCC information, timestamp map, and snapshot timestamp of the export transaction are written to a binary file. When an import of the database table is initiated in a database management system, the database table is reconstructed from the table rows, associated MVCC information, timestamp map, and snapshot timestamp of the export transaction in the binary file.
First claim
Opening claim text (preview).
What is claimed is: 1 . A computer implemented method, comprising: receiving, by at least one processor, a request to export a database table in a database management system; iterating, by the at least one processor, through MVCC information associated with each row in the database table to identify temporary creation and deletion timestamps of rows, each temporary timestamp associated with a database transaction; generating, by the at least one processor, a timestamp map, t…
