Introduction

Background: The proliferation of cloud computing has transformed the landscape of data analytics, enabling organizations to harness the power of distributed computing for real-time insights and decision-making. As data volumes continue to surge, the demand for efficient query optimization and resource management has become paramount. Traditional query optimization techniques, which rely heavily on static rules and manual tuning, often fall short in addressing the dynamic nature of cloud environments. The advent of machine learning and AI technologies offers new avenues for enhancing query optimization, making it possible to adapt to changing workloads and resource availability in real-time. This paper builds on these advancements, presenting a Dynamic Query Optimization Framework that leverages cutting-edge AI and metadata-driven techniques to redefine query processing in cloud environments.

Problem Statement: Despite significant progress in cloud-based query optimization, several challenges remain unaddressed. Current techniques often lack the adaptability required to handle fluctuating workloads and diverse data sources characteristic of multi-cloud environments. The manual tuning and static optimization rules prevalent in traditional systems lead to inefficiencies and increased operational costs. Additionally, the siloed nature of existing query execution engines limits their ability to share intermediate results and optimize resource utilization across multiple queries. These limitations necessitate the development of a more robust, adaptive framework that can dynamically optimize query execution, resource allocation, and data partitioning based on real-time metrics and historical data.

Contributions: This paper introduces a Dynamic Query Optimization Framework that encompasses seven novel and patentable innovations designed to address the aforementioned challenges. The key contributions of this framework include: an AI-powered adaptive query execution engine that leverages reinforcement learning to predict optimal execution paths; a self-optimizing data partitioning and indexing mechanism that restructures data layouts based on query access patterns; a multi-query optimization system with intelligent result sharing to avoid redundant processing; a predictive resource allocation scheduler that dynamically provisions cloud resources to optimize cost-performance balance; a photon-accelerated query execution layer with AI-driven vectorization for ultra-fast processing; a context-aware query optimization engine for multi-cloud environments that leverages cloud-specific configurations; and a real-time query performance monitoring and autonomous optimization framework that continuously refines execution strategies. These contributions collectively enhance query performance, scalability, and cost efficiency in cloud environments.
