Data processing method and apparatus, electronic device, and storage medium

An electronic device, comprising:

• at least one processor;
• and
• a memory communicatively connected with the at least one processor;
• wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to perform a method for data processing, wherein the method for data processing comprises:
• determining a priority of each placement group in a cache pool respectively, and dividing placement groups with the same priority into a same waiting queue;
• constructing a target queue which is initially empty, and in response to determining that a supplementary trigger condition is met, determining placement groups to be retrieved based on a principle that a placement group in a waiting queue with higher priority is retrieved first, retrieving the placement groups to be retrieved from the corresponding waiting queue and adding the placement groups to be retrieved to the target queue;
• and
• in response to determining that the target queue is not empty, iteratively traversing each placement group in the target queue, wherein when traversing each placement group, the placement group is used as a target placement group respectively, and the number of writable objects is determined as a first quantity, and the first quantity of objects retrieved from the target placement group is written to a backend pool.

A non-transitory computer readable storage medium with computer instructions stored thereon, wherein the computer instructions are used for causing a method for data processing, wherein the method for data processing comprises:

• determining a priority of each placement group in a cache pool respectively, and dividing placement groups with the same priority into a same waiting queue;
• constructing a target queue which is initially empty, and in response to determining that a supplementary trigger condition is met, determining placement groups to be retrieved based on a principle that a placement group in a waiting queue with higher priority is retrieved first, retrieving the placement groups to be retrieved from the corresponding waiting queue and adding the placement groups to be retrieved to the target queue;
• and
• in response to determining that the target queue is not empty, iteratively traversing each placement group in the target queue, wherein when traversing each placement group, the placement group is used as a target placement group respectively, and the number of writable objects is determined as a first quantity, and the first quantity of objects retrieved from the target placement group is written to a backend pool.
