grafana/tempo v0.7.0

on GitHub

License Change

• v0.7.0 and future versions are licensed under AGPLv3 #660

Breaking changes

• In an effort to move to byte based limits we removed some limits options and replaced them with byte based ones:
  max_spans_per_trace => max_bytes_per_trace
ingestion_rate_limit => ingestion_rate_limit_bytes
ingestion_burst_size => ingestion_burst_size_bytes
• The Query/QueryFrontend call signature has changed so there will be a query interruption during rollout.

All Changes

• [CHANGE] Update to Go 1.16, latest OpenTelemetry proto definition and collector #546 @mdisibio
• [CHANGE] max_spans_per_trace limit override has been removed in favour of max_bytes_per_trace.
  This is a breaking change to the overrides config section. #612 @annanay25
• [CHANGE] Add new flag -ingester.lifecycler.ID to manually override the ingester ID with which to register in the ring. #625 @annanay25
• [CHANGE] ingestion_rate_limit limit override has been removed in favour of ingestion_rate_limit_bytes.
  ingestion_burst_size limit override has been removed in favour of ingestion_burst_size_bytes.
  This is a breaking change to the overrides config section. #630 @annanay25

Features

• [FEATURE] Add page based access to the index file. #557 @joe-elliott
• [FEATURE] (Experimental) WAL Compression/checksums. #638 @joe-elliott

Enhancements

• [ENHANCEMENT] Add a Shutdown handler to flush data to backend, at "/shutdown". #526 @annanay25
• [ENHANCEMENT] Queriers now query all (healthy) ingesters for a trace to mitigate 404s on ingester rollouts/scaleups.
  This is a breaking change and will likely result in query errors on rollout as the query signature b/n QueryFrontend & Querier has changed. #557 @annanay25
• [ENHANCEMENT] Add list compaction-summary command to tempo-cli #588 @mdisibio
• [ENHANCEMENT] Add list and view index commands to tempo-cli #611 @mdisibio
