Can I use the R API to trigger a dataset build/job?

Vinnie

I want to create an R Shiny application to query data. The data exists in dataiku where a pipeline runs nightly. I would like to add a button to my app that would rebuild my data on an ad-hoc basis. Is this possible? In python it looks like this works. Is there an R equivalent?

import dataiku


project = dataiku.api_client().get_default_project()


dataset = project.get_dataset("my_dataset")


dataset.build()

Hi,
The R API does allow for building datasets/running scenarios; that being said, you have several options to achieve this from R Shiny by interacting with the Python API or a REST API

1) You could create a seperate Webapp API endpoint( Flask or Dash) in the same project that runs the required builds via the Python APIs

https://developer.dataiku.com/latest/tutorials/webapps/common/api/index.html

2) Call this from RShiny via libraries like
library(httr2)library(jsonlite)

url <- "http://<DATAIKU_ADDRESS>:<DATAIKU_PORT>/web-apps-backends/<PROJECT_KEY>/<WEBAPP_ID>/run_scenario"

body_data <- list(scenario_id = "MY_SCENARIO_ID")

resp <- request(url) |>req_headers(Authorization = "Bearer <USE_YOUR_API_KEY>","Content-Type" = "application/json") |>req_body_json(body_data) |>req_perform()

The other option is to run Python code directly from your rShiny webapp using reticulate
