Multi-language mixed stream processing method and device

The embodiment of the invention provides a multi-language mixed stream processing method and device. According to the specific technical scheme, the method comprises the steps that JobGraph (work graph) is generated according to the multi-language mixed flow, and at least one work node in the JobGraph is provided with a language type attribute tag; according to the JobGraph, generating an Execution Graph (Execution Graph), wherein the Execution Graph comprises task nodes of different language types; and respectively creating independent task processes for the task nodes of different language types so as to execute processing tasks corresponding to the task nodes. 本说明书实施例提供了一种多语言混合流处理的方法和装置。具体技术方案包括：依据多语言混合流生成JobGraph（工作图），所述JobGraph中的至少一个工作节点具有语言类型属性标签；依据所述JobGraph生成Execution Graph（执行图），所述Execution Graph中包含不同语言类型的任务节点；针对不同语言类型的任务节点分别创建独立的任务进程以执行各任务节点对应的处理任务。
