DATA PROCESSING METHOD, DATA WRITING METHOD, AND RELATED APPARATUS

摘要

Embodiments of the present invention disclose a data processing method, including: acquiring to-be-stored data in a data table in a columnar database; dividing and/or combining the to-be-stored data according to space of an allocated disk cylinder; and storing same-row data of the to-be-stored data in a same disk cylinder, and in the disk cylinder, successively storing data in each section of columns. Correspondingly, the present invention further discloses a data writing method and a related apparatus and device. A technical problem in the prior art that a write speed is slow when a columnar database is running is resolved by using the present invention, which greatly improves write efficiency of a columnar database. In addition, direct parallel reading or writing may also be implemented by means of hardware marking.
