19 days ago 高效码农Fluxus: The High-Performance Rust Stream Processing Engine Why Stream Processing Engines Matter In today’s data-driven world, real-time processing capabilities have become a critical competitive advantage. Whether monitoring financial transactions, analyzing IoT device data, or tracking user behavior, traditional batch processing systems fail to meet millisecond-level response requirements. This is where stream processing engines deliver value—they continuously process unbounded data streams to enable true real-time insights. Core Capabilities of Fluxus Fluxus is a lightweight Rust-based stream processing framework with these foundational capabilities: Exceptional Processing Performance Leverages Rust’s zero-cost abstractions Designed without garbage collection mechanisms Maximizes efficiency with memory safety guarantees Flexible …
How to Slash Memory Usage by 77%: Pydantic JSON Optimization Guide
1 months ago 高效码农Efficiently Loading Large JSON Data with Pydantic: A Memory Optimization Guide Introduction: The JSON Memory Bottleneck Imagine you need to process a 100MB JSON file containing customer records using Python. You choose Pydantic for data validation, only to discover your program consumes 2GB of RAM—20 times the file size! At 10GB, this approach would require 200GB of memory, crashing most systems. This guide reveals why this happens and provides actionable solutions to optimize memory usage. Understanding the Memory Overhead Technical Breakdown Dual Memory Consumption Parsing Overhead: Most JSON parsers load the entire file into memory, creating intermediate structures (e.g., Python …
