The embodiment of the invention provides a file merging method and device, equipment, a medium and a product, and relates to the field of
big data. The method comprises the following steps: acquiring configuration parameters for file merging from a configuration table, wherein the configuration parameters comprise a target file name, a sub-
library file name
list and a file type; comparing the
effective date of the configuration parameter with the current
system date, using the new configuration parameter when the
system date is greater than or equal to the
effective date, otherwise using the old configuration parameter; and based on the used configuration parameters, performing merging
processing on the sub-
library files to generate a target file. According to the scheme, the configuration parameters are changed through the
effective date, errors of manual merging are reduced, the configuration parameters are managed through the configuration table, the merging rule can be dynamically adjusted according to service requirements, program codes do not need to be modified, and therefore the file merging efficiency is improved.
