nl_tokens: NOTE : This is passed exId instead of executionContext like addWorkers and removeWorkers . I don t know why just dealing with it .
pl_tokens: async function removeWorkers ( exId , numWorkers ) { await k8s . scaleExecution ( exId , numWorkers , 'remove' ) ; return { <mask> : 'remove' , ex_id : exId , workerNum : numWorkers } ; }
