We’ve introduced several enhancements to Projects, providing greater flexibility and control over how you interact with data. These updates include:

  • : Your selected columns will now remain consistent across sessions, ensuring a more seamless workflow.

  • : Easily filter data directly from the table view using metadata attributes.

  • Custom Time Ranges: You can now specify custom time ranges to filter traces and spans.

  • Root Span Filter for Spans: Improved filtering options allow you to filter by root spans, helping to isolate and debug issues more effectively.

  • : Quickly apply common metadata filters for faster navigation.

  • : Major speed improvements in project tracing views & visibility into database usage in settings

Improvements and Bug Fixes πŸ›

: Query to get number of spans for each trace

: Show + n more spans in trace table

: Add Token component

: Remove double fetching of spans

: Don't fetch new traces when the traces slideover is visible

: Fix scrolling on trace tree
