Electronic apparatus, data chain archiving method, system and storage medium

An electronic apparatus comprising a memory, a processor connected to the memory and a processing system stored on the memory and running on the processor, the processing system, when being executed by the processor, performing the following steps:

• a first writing step, dividing an original data table in a database into a first quantity of preset partitions, and writing finished data in the partitions into a first temporary table which is pre-established according to a predetermined first processing mode by utilizing a second quantity of preset parallel threads, wherein the first quantity is larger than or equal to the second quantity;
• a second writing step, obtaining data with superior and subordinate association in the first temporary table by utilizing a single thread after all the finished data in the partitions is written in the first temporary table, and writing the data with the superior and subordinate association into a second temporary table which is pre-established;
• an archiving step, dividing the second temporary table into a third quantity of preset partitions after all the data in the first temporary table is processed by utilizing the single thread, archiving the data in the partitions of the second temporary table into a pre-established archive table in the database according to a predetermined second processing mode by utilizing a fourth quantity of preset parallel threads, and deleting the data correspondingly written in the archive table in the original data table, wherein the third quantity is larger than or equal to the fourth quantity.
