Abstract
The invention discloses a data partition storage method and device. The method comprises the steps: initializing a partition table for storing genemutation sites in a predetermined data warehouse; dividing the partition table into a plurality of subareas according to the data interval corresponding to each genemutation site in the plurality of genemutation sites; obtaining a starting point numerical value and an end point numerical value of a to-be-stored target gene mutation site; and matching the target gene mutation site based on the starting point numerical value and the terminal pointdata of the target gene mutation site and storing the target gene mutation site in one or more subareas of the partition table. The technical problems that in the related art, the number of partitionsof human whole genome variation detection result data in a hive data warehouse is too large or too small, and the partition data size is unbalanced are solved.
Description
technical field [0001] The present invention relates to the technical field of biological information, in particular to a data partition storage method and device. Background technique [0002] With the rapid development of life science and gene sequencing technology, the Moore's law of sequencing cost has decreased, and the data output capacity has been greatly improved. With the deepening of scientific research, the diagnosis, treatment and screening of diseases such as cancer and genetic diseases not only focus on the influence of single genes on diseases, but also include the complex mechanism of multiple genes on diseases. More and more countries Initiated research on the application of human whole genome sequencing to human health. The length of the whole human genome is 3 billion bases, and storing a person's 30X WGS (whole genome sequencing) data probably requires more than 90G of hard disk space. Therefore, as the sequencing samples increase, the accumulated data ...
