January 2026 monthly summary for grafana/pyroscope: Key features delivered: - Data accuracy improvement: aggregate exemplar values by profile ID and timestamp. Updated deduplication logic to aggregate values instead of discarding them, ensuring multiple entries are correctly represented in the final output. Added tests to validate the new behavior. - Performance benchmarking suite for exemplar queries: Introduced benchmarks for timeseries queries focusing on exemplars, including benchmark fixtures, execution, and validation to ensure exemplar overhead remains within acceptable limits. Major bugs fixed: - Fixed deduplication behavior that could discard multiple exemplar entries for the same profile and timestamp; now aggregates values to preserve data integrity across splits. - Expanded test coverage to validate the new aggregation behavior and benchmarks, reducing regression risk. Overall impact and accomplishments: - Significantly improved data integrity for exemplars, enabling more accurate analytics and reporting. - Established a performance baseline for exemplar-related queries, enabling data-driven optimization and faster issue diagnosis. - Reduced risk of data skew due to deduplication by implementing robust aggregation logic and tests. Technologies/skills demonstrated: - Data deduplication and aggregation logic for timeseries exemplars. - Test-driven development with added unit/integration tests. - Benchmarking and performance measurement for timeseries queries. - Cross-functional collaboration demonstrated via commits in grafana/pyroscope.
