The Expectations Gallery is a Great Expectations staple, and we’ve heard your feedback about how it could serve you better. We’re excited to finally share what we’ve been working on in response.
The new Expectations Gallery is a streamlined and simplified update that aims to vastly improve your user experience.
What’s different?
In each Expectation, you’ll now see more usage and implementation details. Each Expectation now has more detailed information, including sample data with passing and failing examples.
Of course, details can change over time. So we’re developing a process to ensure updated information reaches the gallery faster.
As you browse the gallery, you’ll also encounter our overhauled search and filter functionality. It’s more intuitive than the previous version and includes additional capabilities to filter by data quality issue type—making it way easier to find the Expectations you need.
Speaking of browsing the gallery, you’ll also notice that we’ve pruned the available Expectations for now, but we’ll regularly be adding more as we complete their documentation and usage/implementation information. Having detailed documentation and thorough testing for each Expectation in the gallery ensures that the gallery will remain a reliable resource for GX users.
Available now
We’ve started out the new Expectations Gallery with 47 of the most widely used and best-supported Expectations.
We did this, rather than immediately move over all 300+ Expectations from the original gallery, because we consistently heard the same feedback about the gallery experience: that the sheer volume of Expectations in the old gallery was overwhelming, not empowering.
That’s not the experience that we want the GX community to have! So as a first step, we’re starting off the new Expectations Gallery with this core set of broadly applicable and GX-supported Expectations.
Where is the new gallery?
It’s at the same place: https://greatexpectations.io/expectations.
The future of the gallery
First of all, we’re going to phase in additional Expectations as their documentation is completed. So if your favorite Expectation isn’t in the gallery, keep an eye out.
And if you need it right away, you can access the previous gallery and all its Expectations in the Legacy Gallery.
If you have ideas about what Expectations we should add next or feedback about the new gallery, we want to hear them! You can reach us at our Slack #gx-feedback channel.
