Breaking Changes

  • Fix issue where tempo drops the entire batch if one trace triggers an error #2571 (@ie-pham)
    Distributor now returns 200 for any batch containing only trace_too_large and max_live_traces errors
    The number of discarded spans are still reflected in the tempo_discarded_spans_total metrics
  • Deprecating vParquet v1 #3377 (@ie-pham)
    vParquet can no longer be explicitly configured as a block version. Tempo 2.4 will continue to read these blocks. Support will be dropped entirely in 2.5. The current/default block version is vParquet3.
  • Major cache refactor to allow multiple role based caches to be configured #3166 (@joe-elliott).
    Deprecate the following fields. These have all been migrated to a top level "cache:" field. 
    storage:
  trace:
    cache:
    search:
      cache_control:
    background_cache:
    memcached:
    redis:
