* Loki query from Tempo UI - add query type selector to tempo - introduce linkedDatasource concept that runs queries on behalf of another datasource - Tempo uses Loki's query field and Loki's derived fields to find a trace matcher - Tempo uses the trace-to-logs mechanism to determine which dataource is linked Loki data loads successfully via tempo Extracted result transformers Skip null values Show trace on list id click Query type selector Use linked field trace regexp * Review feedback
