Roadmap update

Erik Hencier, a senior product manager at GX, reviewed what we’ve been working on recently in GX and what’s up next!

Lately, we’ve been working on: 

  • Managing Data Sources and Assets in the GX Cloud UI

  • A way to use time-based splitting to validate a subset of your SQL data in the GX Cloud UI

  • Viewing an Expectation’s edit history in the GX Cloud UI

Up next:

  • A new Expectation for referential integrity, a long-standing request we’re excited to bring to fruition!

  • Faster team setup in GX Cloud using org-based agents


Mollie Pettit, GX's senior community manager, shared some announcements:

  • We’re hiring! We currently have openings for a project marketing manager, senior software engineer, and senior UX designer. See the role details and apply here: 

  • Reminder: We’re temporarily pausing PRs until GX OSS 1.0 is released! Our GX 1.0 work will be making major changes to the codebase, and we don’t want any contributors to put in time and effort only for their code to immediately get broken by a change. Please hold on to your ideas—we’re excited to begin accepting PRs again after the GX OSS 1.0 release.

New GX event calendar
