The invention discloses a sequencing method based on
mass data, which belongs to the technical field of data sequencing, and comprises the following steps:
data splitting: splitting a
data source M to be sequenced into N files;
block sorting amp is carried out; extracting: sorting each file according to the sorting fields, and extracting the first X pens of each file; merging and sorting: integrating the sorted and extracted data together, sorting, and storing the first X rows into a
result set; and displaying: displaying the
result set data in sequence. According to the method, the success of sorting
processing can be ensured, and the conditions of memory overflow errors and
system crash or extremely slow change are avoided; in the aspect of performance, the
processing and sorting quantity is greatly reduced, computing resources can be saved, the CPU
utilization rate can be reduced, the
response time can be shortened, and remarkable
delay generated in the sorting process is avoided; in the aspects of maintenance and management, the
system architecture can be simplified, and the level of a fault-tolerant mechanism can be reduced, so that the complexity of
system design and maintenance is reduced.
