Method of resource adjustment for service cluster, electronic device and storage medium

An electronic device, comprising:

• at least one processor and a memory, wherein the memory stores machine-readable instructions executed by the at least one processor, the at least one processor is configured to execute the machine-readable instructions stored in the memory, and when the machine-readable instructions are executed by the at least one processor, the at least one processor is caused to execute:
• determining resource adjustment information for the service cluster according to a task quantity of streaming data processing tasks to be processed, wherein the resource adjustment information comprises a resource adjustment operation that is required to be executed for processing the streaming data processing tasks and a corresponding parallelism degree to be adjusted;
• the parallelism degree to be adjusted is used to indicate a resource quantity that is required to be adjusted by the service cluster;
• determining a core quantity to be adjusted corresponding to central processor units and a second quantity of computing nodes to be adjusted, according to the parallelism degree to be adjusted, a first quantity of the computing nodes that have been created in the service cluster, and a resource utilization rate of central processor units in each computing node that has been created;
• and
• executing the resource adjustment operation according to the core quantity to be adjusted and the second quantity, and obtaining a service cluster subject to resource adjusting, wherein the service cluster subject to resource adjusting is used to process streaming data processing tasks under the task quantity.

A non-transient computer-readable storage medium, wherein the non-transient computer-readable storage medium stores computer programs, and when the computer programs are run by an electronic device, the electronic device is caused to execute:

• determining resource adjustment information for the service cluster according to a task quantity of streaming data processing tasks to be processed, wherein the resource adjustment information comprises a resource adjustment operation that is required to be executed for processing the streaming data processing tasks and a corresponding parallelism degree to be adjusted;
• the parallelism degree to be adjusted is used to indicate a resource quantity that is required to be adjusted by the service cluster;
• determining a core quantity to be adjusted corresponding to central processor units and a second quantity of computing nodes to be adjusted, according to the parallelism degree to be adjusted, a first quantity of the computing nodes that have been created in the service cluster, and a resource utilization rate of central processor units in each computing node that has been created;
• and
• executing the resource adjustment operation according to the core quantity to be adjusted and the second quantity, and obtaining a service cluster subject to resource adjusting, wherein the service cluster subject to resource adjusting is used to process streaming data processing tasks under the task quantity.
