1 Introduction
Aerospike is a distributed NoSQL database system that is fast, simple, and scalable. This article mainly introduces Aerospike's performance optimization method, and gives architectural optimization suggestions based on practical experience. I hope that through the detailed elaboration of the article, readers can benefit a lot.
2. Explanation of basic concepts and terms
Introduction to Aerospike
Aerospike is a distributed NoSQL database system provided by Intel and Google. Its main advantages are as follows:
- Strong scalability: The cluster scale can dynamically increase or decrease nodes without interrupting services.
- Data persistence and fast recovery capability: data is stored in memory and can be quickly restored through hot backup.
- Simple and easy to use: Provide consistent API interface and rich data type support, users can use it with simple configuration.
- Ultra-high-speed access speed: The underlying C/C++ development framework is adopted, with ultra-high throughput and low-latency access.
- Open source and free: The code is open source and free for use in commercial products, internal projects, research, and education.
Basic Concepts and Terminology of Aerospike
Namespace
Every Aerospike cluster has a default namespace. If you need to create multiple database instances, you should create a new namespace for each instance. A namespace is similar to a database in a relational database where different tables can be created.
Set (collection)
Sets are the most basic data structure in Aerospike. The concept of a collection is similar to relational data
