Worked on enhancing time-series analytics for the SigNoz/signoz repository by implementing support for both delta and cumulative temporality in metric queries. This feature extended the existing temporality layer to allow time-range based retrieval and cross-temporality analytics, addressing the need for more flexible and accurate data analysis. The approach involved updating FetchTemporality and FetchTemporalityMulti functions to accept time range parameters, enabling interval-based data retrieval. Leveraging Go and Python for backend development and database management, the work improved the analytics capabilities for dashboards and reports, allowing users to aggregate and analyze metrics across different temporalities within specified intervals.
