IDEMPOTENT TASK EXECUTION IN ON-DEMAND NETWORK CODE EXECUTION SYSTEMS

机译:按需网络代码执行系统中的优势任务执行

摘要

Systems and methods are described for handling requests to execute idempotent code in an on-demand code execution system or other distributed code execution environment. Idempotent code can generally include code that produces the same outcome even when executed multiple times, so long as dependencies for the code are in the same state as during a prior execution. Due to this feature, multiple executions of idempotent code may inefficiently use computing resources, particularly in on-demand code execution system (which may require, for example, generation and provisioning of an appropriate execution environment for the code). Aspects of the present disclosure enable the on-demand code execution system to process requests to execute code by verifying whether dependency states associated with the code have changed since a prior execution. If dependency states have not changed, no execution need occur, and the overall computing resource us of the on-demand code execution system is decreased.
