Cross-Event Querying lets you refine your search for spans by joining on additional Sentry event types connected by a trace (currently, span and log events are supported).
So now you can ask questions like
“show me webhooks that write to a database”:

Or, “show me backend services that log errors”:

Cross Event querying is currently available for Early Adopters. To try it out, open Trace Explorer and click the plus button next to the search bar.
Please reach out on GitHub or Discord if you have any feedback.
