Method and apparatus for pre-aggregating time series data

An apparatus for pre-aggregating time series data, comprising a processor, a memory, wherein the memory is configured to store an instruction, and the processor is configured to invoke the instruction in the memory to perform operations comprising:

• obtaining at least one piece of time series data from a first device, wherein the first device is a generation device of the at least one piece of time series data, or the first device is a node device of a time series database, and any one of the at least one piece of time series data comprises an identifier;
• determining a pre-aggregation method based on the identifier of the at least one piece of time series data, wherein a preset binding relationship exists between the pre-aggregation method and the identifier of the at least one piece of time series data;
• processing the at least one piece of time series data using the pre-aggregation method, to generate pre-aggregated data;
• writing the pre-aggregated data and the at least one piece of time series data into a memory;
• and
• when a usage of the memory satisfies a trigger condition, writing the pre-aggregated data and the at least one piece of time series data into a disk.

A computer program product, wherein when the computer program product is executed by a processor, operations are caused to be performed:

• obtaining at least one piece of time series data from a first device, wherein the first device is a generation device of the at least one piece of time series data, or the first device is a node device of a time series database, and any one of the at least one piece of time series data comprises an identifier;
• determining a pre-aggregation method based on the identifier of the at least one piece of time series data, wherein a preset binding relationship exists between the pre-aggregation method and the identifier of the at least one piece of time series data;
• processing the at least one piece of time series data using the pre-aggregation method, to generate pre-aggregated data;
• writing the pre-aggregated data and the at least one piece of time series data into a memory;
• and
• when a usage of the memory satisfies a trigger condition, writing the pre-aggregated data and the at least one piece of time series data into a disk.
