- Optimizely X Full Stack
THIS ARTICLE WILL HELP YOU:
- Understand datafile versioning
- Debug and troubleshoot an Optimizely X Full Stack experiment
To maintain backwards compatiblity with older SDK versions, Optimizely maintains multiple versions of the datafile. Datafile versioning ensures that apps that haven't been upgraded to the latest version of the SDK are still able to run experiments. For each SDK project, Optimizley uploads the datafile once per datafile version.
For example, for project ID "123," if we have 3 versions of the datafile, we will upload the following three files to the CDN:
The Optimizely X Dashboard will always show the path to the latest datafile version. In this case, that would be https://cdn.optimizely.com/public/12...tafile_v3.json. The latest version would also be accessible at https://cdn.optimizely.com/json/123.json.
If you’re using Optimizely’s SDKs to manage synchronizing the datafile from Optimizely, you don’t need to interface with different datafile versions directly. The SDK will make sure to use older versions of the datafile for older versions of the SDK.
Here's our developer documentation, where you'll find code samples, full references for our SDKs, and getting started guides.
