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.
