jaeger v1.20.0 Release Notes

• Backend Changes

  💥 Breaking Changes

  • 🔧 Configurable ES doc count (#2453, @albertteoh)

    The --es.max-num-spans flag has been deprecated in favour of --es.max-doc-count. --es.max-num-spans is marked for removal in v1.21.0 as indicated in the flag description.

    If both --es.max-num-spans and --es.max-doc-count are set, the lesser of the two will be used.

    The use of --es.max-doc-count (which defaults to 10,000) will limit the results from all Elasticsearch queries by the configured value, limiting counts for Jaeger UI:

    • Services
    • Operations
    • Dependencies (edges in a dependency graph)
    • Span fetch size for a trace

  • 👀 The default value for the flag query.max-clock-skew-adjustment has changed to 0s, meaning that the clock skew adjustment is now disabled by default. See #1459.
