Wix experiment system (A/B test and feature toggle framework)

Petri

Petri is Wix’s holistic experiment system, it covers the lifecycle of product experimenting including A/B tests and feature toggles.

Petri is used at large scale at Wix, supporting dozens of daily changes (instantly affecting production, no deployment needed).

Main features

• Create and gradually open A/B tests to affect your user’s experience. This feature helps our Product Managers collect data on user behavior before making decisions.
• Create Feature Toggles to control inner implementation details. This feature helps our developers gradually roll out features.
• Define filters to determine what users will be included in your defined experiments. Our filters include language, geo, user-agent, individual user IDs (usually used for QA) and more. Custom filters can also be added.
• Conduction values are periodically reported back to the server to enable quick triaging as well as automatic pausing if a limit to the number of users is specified.

Reduce the number of transitive dependencies in laboratory-servlet-api-integration

We are evaluating using petri in our environment and one issue we have run into is the number of transitive dependencies that are included in both the compile and runtime classpath when adding "laboratory-servlet-api-integration" to our projects.

I was able to prune these down some with exclusions (I'm using gradle)

compile("com.wixpress.common:laboratory-servlet-api-integration:1.19.0-SNAPSHOT") {
exclude group: 'org.eclipse.jetty'
exclude module: 'petri-test-utils'
}

I am hoping for some help to identify which other transitive dependencies may be excluded from the client libraries.

Thanks in advance for any help!

For reference, here is the dependency graph spit out by gradle:

Is this project being actively maintained?

Hi! I'm interested in using Wix's awesome open source projects. I notice that Petri did not move from wix-incubator to wix. Is this project being actively maintained for the open source community? Thank you! 😄
