Method, apparatus, and management node for managing data in partition table, and storage medium

A method comprising:

• obtaining a creation duration range of data of a target partition in a partition table, wherein the creation duration range is a combination of a minimum duration and a maximum duration, wherein the minimum duration is a first distance between a maximum time in a creation time range and a current time point, and wherein the maximum duration is a second distance between a minimum time in the creation time range and the current time point;
• and
• altering, when the creation duration range meets a predetermined time range of a first storage stage, the data that have been stored based on a second storage policy corresponding to a second storage stage,
• wherein the second storage stage is to be stored based on a first storage policy corresponding to the first storage stage,
• wherein a first storage performance of the first storage stage is lower than a second storage performance of the second storage stage,
• wherein the first storage stage is a warm data storage stage when the second storage stage is a hot data storage stage, and
• wherein the first storage stage is a cold data storage stage when the second storage stage is the warm data storage stage.

A management node comprising:

• a memory configured to store instructions;
• and
• a processor coupled to the memory and configured to execute the instructions to cause the management node to:
• obtain a creation duration range of data of a target partition in a partition table, wherein the creation duration range is a combination of a minimum duration and a maximum duration, wherein the minimum duration is a first distance between a maximum time in a creation time range and a current time point, and wherein the maximum duration is a second distance between a minimum time in the creation time range and the current time point;
• obtain a geographical area to which the target partition belongs, historical access information of the target partition, or a service type of the target partition;
• and
• alter, when the creation duration range meets a predetermined time range of a first storage stage and when a preset condition is met, the data that have been stored based on a second storage policy corresponding to a second storage stage,
• wherein the second storage stage is to be stored based on a first storage policy corresponding to the first storage stage,
• wherein a first storage performance of the first storage stage is lower than a second storage performance of the second storage stage, and
• wherein the preset condition is that the geographical area is a target area, the historical access information meets a target condition, or the service type is a target service type.

A management node comprising:

• and
• a processor coupled to the memory and configured to execute the instructions to cause the management node to:
• obtain a creation duration range of data of a target partition in a partition table, wherein the creation duration range is a combination of a minimum duration and a maximum duration, wherein the minimum duration is a first distance between a maximum time in a creation time range and a current time point, and wherein the maximum duration is a second distance between a minimum time in the creation time range and the current time point;
• and
• alter, when the creation duration range meets a predetermined time range of a first storage stage, the data that have been stored based on a second storage policy corresponding to a second storage stage,
• wherein the second storage stage is to be stored based on a first storage policy corresponding to the first storage stage,
• wherein a first storage performance of the first storage stage is lower than a second storage performance of the second storage stage,
• wherein the first storage stage is a warm data storage stage when the second storage stage is a hot data storage stage, and
• wherein the first storage stage is a cold data storage stage when the second storage stage is the warm data storage stage.
