SingleStore (MemSQL) Basics

1. Introduction

SingleStore, previously known as MemSQL, is a distributed, relational NewSQL database designed for speed and scalability. It supports both transactional and analytical workloads, making it an excellent choice for real-time applications.

2. Key Concepts

• **Distributed Architecture:** Data is stored across multiple nodes for scalability.
• **In-Memory Processing:** Leverages in-memory storage for faster data access.
• **SQL Compatibility:** Supports ANSI SQL, allowing for easy integration with existing SQL tools.

3. Installation

3.1. System Requirements

Ensure your system meets the following requirements:

• 64-bit Linux OS (CentOS, RHEL, Ubuntu)
• At least 8 GB of RAM
• Minimum 4 CPU cores

3.2. Installation Steps

Follow these steps to install SingleStore:

1. Download the SingleStore installation package from the official website.
2. Run the installation script:

bash 

3. Start the SingleStore service:

memsql-admin start

4. Data Model

SingleStore supports both row and columnar storage models. This flexibility allows for optimized performance based on the workload.

To create a new table:

CREATE TABLE users (
    id INT PRIMARY KEY,
    name VARCHAR(255),
    email VARCHAR(255)
);

5. Queries

SingleStore allows you to execute standard SQL queries. Here's a basic example:

SELECT * FROM users WHERE email LIKE '%@example.com';

6. Best Practices

• Use indexing to improve query performance.
• Regularly backup your database.
• Scale horizontally by adding more nodes as needed.
