React Query 3: A Guide to Fetching and Managing Data
Article Introduction:Simplify data acquisition for front-end CRUD applications using React Query
Building a front-end CRUD application is easy at first, but as functionality increases, complexity increases rapidly. For each API endpoint, state management, synchronization, caching, and error handling are required. This article will introduce a library called React Query and how it can help solve all of these problems. The library claims to be a "missing data acquisition library" and provides "server state management" for your React application.
We will use a complete React Query demo project to learn the core features that the library provides. You can then apply this knowledge to your own project. First, in

MongoDB index optimization strategy to accelerate query performance
Article Introduction:MongoDB index optimization strategy to make your query fly! MongoDB's query speed is slow? Database card into a dog? Don't worry, this article will take you to understand the MongoDB index optimization strategy in an easy-to-understand way, allowing you to completely get rid of the bottleneck of query performance. After reading this article, you can not only master the essence of indexing, but also become a master of MongoDB performance tuning and show off your skills in front of your colleagues! Let’s talk about the conclusion first: the index is like a library directory. Without it, you can only search for information pages by page, which is extremely inefficient; with it, you can quickly locate the target information and query at a high speed! In MongoDB, indexing is just such a thing. It can significantly improve query speed, but improper use can backfire and even reduce performance. Basics:

Building Data Catalogs with Python
Article Introduction:The reasons for building data directories in Python include its powerful data processing capabilities, rich library support and automation advantages. 1. Python can efficiently extract metadata from databases, file systems and cloud services; 2. Provide flexible data organization methods, such as structured storage and visual display; 3. Support automated update mechanisms to ensure directory timeliness. SQLAlchemy can obtain the database table structure, use pandas or pyarrow to read the file schema, then store it in JSON or database form, and build a query interface with Flask/FastAPI, and combine cronjob or Airflow to achieve timed updates, thereby building a complete and dynamically maintained data directory system
