Data processing method and related device

A data processing apparatus, comprising at least one memory storing instructions and at least one processor coupled to the at least one memory to execute the instructions to cause the data processing apparatus to:

• obtain a base table and M aggregate tables, wherein the base table comprises data stored by the data processing apparatus, the M aggregate tables are obtained by processing, based on M aggregation definitions, the data comprised in the base table, the M aggregate tables are in one-to-one correspondence with the M aggregation definitions, the M aggregation definitions are different, each of the M aggregate definitions comprises a key-value pair, each of the M aggregate definitions indicate a manner of processing the data comprised in the base table, and M is an integer greater than or equal to 2;
• determine N to-be-merged aggregate tables from the M aggregate tables based on keys comprised in the M aggregation definitions, wherein N is an integer greater than or equal to 2 and less than or equal to M;
• and
• merge the N to-be-merged aggregate tables to obtain a merged aggregate table, wherein a data amount of the merged aggregate table is less than a sum of data amounts of the N to-be-merged aggregate tables.

A non-transitory computer-readable storage medium, wherein the computer-readable storage medium comprises computer program instructions, and when the computer program instructions are run by a compute device cluster, the compute device cluster is caused to:

• obtain, by the compute device cluster, a base table and M aggregate tables, wherein the base table comprises data actually stored by the network device, the M aggregate tables are obtained by processing, based on M aggregation definitions, the data comprised in the base table, the M aggregate tables are in one-to-one correspondence with the M aggregation definitions, the M aggregation definitions are different, each of the M aggregate definitions comprises a key-value pair, each of the M aggregate definitions indicates a manner of processing the data comprised in the base table, and M is an integer greater than or equal to 2;
• determine, by the compute device cluster, N to-be-merged aggregate tables from the M aggregate tables based on keys comprised in the M aggregation definitions, wherein N is an integer greater than or equal to 2 and less than or equal to M;
• and
• merge, by the compute device cluster, the N to-be-merged aggregate tables to obtain a merged aggregate table, wherein a data amount of the merged aggregate table is less than a sum of data amounts of the N to-be-merged aggregate tables.
