Histogram Data Retrieval with Mixed Granularity Optimization

Executive Summary This document describes an optimized approach for retrieving histogram data stored across multiple temporal granularities (5-second, 1-minute, 1-hour, 1-day, 1-week, 1-month) when querying with timezone-specific ranges. The solution leverages histogram aggregation properties to minimize data retrieval overhead while maintaining statistical accuracy through intelligent granularity selection and bucket merging. Problem Statement Histogram data is …

Time Series Data Retrieval with Mixed Granularity Optimization

Executive Summary This document describes an optimized approach for retrieving time series event counter data stored in multiple granularities (5-second, 1-minute, 1-hour, 1-day, 1-week, 1-month) when querying with timezone-specific ranges. The solution minimizes data retrieval overhead while ensuring precise boundary coverage through intelligent granularity selection. Problem Statement Time series data is stored in UTC-aligned segments …

Farewell to a Giant: The Sad, Slow Demise of the Airbus A380

In the annals of aviation, there are few aircraft that have inspired awe quite like the Airbus A380. Colossal, graceful, and whisper-quiet, the double-decked superjumbo was more than just a plane. It was a flying cathedral of engineering brilliance and a symbol of humanity’s unrelenting ambition to reach higher, farther, and in greater comfort than …

Cauldron: Embracing Dependency Inversion through Dependee-Centric Dependency Declarations

Abstract: Traditional dependency management paradigms focus on dependencies declaring their reliance on dependees, often leading to tightly coupled systems and intricate dependency graphs. This paper introduces a revolutionary approach to dependency inversion with Cauldron, a cutting-edge build tool that prioritizes dependees in dependency declarations. By allowing dependencies to declare all dependees that rely on them, …
