I believe even if it is where to be made available as part of NiFi REST API, I think it is internally going to call the start and stop APIs.

答复: Re: Re: Re: 答复: Re: Is there a REST API to run a dataflow on demand?
Yes, that is what I do currently. But I think it will be better if NiFi can support this feature natively. 发件人: "Andrew Grande" <apere...@gmail.com> 收件人: dev@nifi.apache.org 日期: 2018/02/23 09:07 主题: Re: Re: Re: 答复: Re: Is there a REST API to run a dataflow on demand? One could write a script and call it in 1 step. I don't believe there is anything available OOTB.

One could write a script and call it in 1 step. I don't believe there is anything available OOTB.
