Yahoo Gemini to Superset

This page provides you with instructions on how to extract data from Yahoo Gemini and analyze it in Superset. (If the mechanics of extracting data from Yahoo Gemini seem too complex or difficult to maintain, check out Stitch, which can do all the heavy lifting for you in just a few clicks.)

What is Yahoo Gemini?

Yahoo Gemini is the advertising platform for Verizon Media's owned and operated web properties: Yahoo, AOL, Tumblr, TechCrunch, and the Huffington Post, along with their publishing partners.

Getting data out of Yahoo Gemini

Gemini provides a RESTful API that lets developers retrieve data stored in the platform about advertisers, ads, campaigns, and more. For example, to retrieve information about an ad, you would call GET https://api.gemini.yahoo.com/v3/rest/ad/id/.

Sample Yahoo Gemini data

Here's an example of the kind of response you might see with a query like the one above.

{
  "errors": null,
  "response": {
      "id": 320325,
      "description": "latest version",
      "adGroupId": 46758,
      "status": "ACTIVE",
      "campaignId": 31369,
      "advertiserId": 87292,
      "title": "batch call ad 2",
      "landingUrl": "http://www.yahoo.com",
      "imageUrl": "http://image.jpg",
      "sponsoredBy": "Sandboxes Inc",
      "displayUrl": "http://www.yahoo.com",
      "imageUrlHQ": null,
      "contentUrl": null,
      "callToActionText": null,
      "videoPrimaryUrl": null,
      "adName": null,
      "impressionTrackingUrls": {
                 "impression": null
              }
  }
}

Preparing Yahoo Gemini data

If you don't already have a data structure in which to store the data you retrieve, you'll have to create a schema for your data tables. Then, for each value in the response, you'll need to identify a predefined datatype (INTEGER, DATETIME, etc.) and build a table that can receive them. The Yahoo Gemini documentation should tell you what fields are provided by each endpoint, along with their corresponding datatypes.

Complicating things is the fact that the records retrieved from the source may not always be "flat" – some of the objects may actually be lists. In these cases you'll likely have to create additional tables to capture the unpredictable cardinality in each record.

Keeping Yahoo Gemini data up to date

At this point you've coded up a script or written a program to get the data you want and successfully moved it into your data warehouse. But how will you load new or updated data? It's not a good idea to replicate all of your data each time you have updated records. That process would be painfully slow and resource-intensive.

The key is to build your script in such a way that it can identify incremental updates to your data. Once you've take new data into account, you can set your script up as a cron job or continuous loop to keep pulling down new data as it appears.

From Yahoo Gemini to your data warehouse: An easier solution

As mentioned earlier, the best practice for analyzing Yahoo Gemini data in Superset is to store that data inside a data warehousing platform alongside data from your other databases and third-party sources. You can find instructions for doing these extractions for leading warehouses on our sister sites Yahoo Gemini to Redshift, Yahoo Gemini to BigQuery, Yahoo Gemini to Azure SQL Data Warehouse, Yahoo Gemini to PostgreSQL, Yahoo Gemini to Panoply, and Yahoo Gemini to Snowflake.

Easier yet, however, is using a solution that does all that work for you. Products like Stitch were built to move data from Yahoo Gemini to Superset automatically. With just a few clicks, Stitch starts extracting your Yahoo Gemini data via the API, structuring it in a way that's optimized for analysis, and inserting that data into a data warehouse that can be easily accessed and analyzed by Superset.
