COMPRESSING A MULTI-VERSION DATABASE

摘要

Managing a multi-version database is provided. A logical record identifier to physical record row identifier indirection mapping table on a solid-state storage device is extended to include a plurality of delta blocks. A delta block within the plurality of delta blocks is maintained for each primary key in a plurality of primary keys associated with a data table on a magnetic hard disk storage device.

主权项

1. A data processing system for managing a multi-version database, the data processing system comprising:
a bus system; a storage device connected to the bus system, wherein the storage device stores computer readable program code; and a processor unit connected to the bus system, wherein the processor unit executes the computer readable program code to extend a logical record identifier to physical record row identifier indirection mapping table on a solid-state storage device to include a plurality of delta blocks; and maintain a delta block within the plurality of delta blocks for each primary key in a plurality of primary keys associated with a data table on a magnetic hard disk storage device.
