TD Database Tutorial: Getting Started with a Powerful Open-Source Distributed Database141

Introduction

TD Database (TDD) is a lightweight, massively parallel, open-source distributed database designed for high concurrency and ultra-low latency transactions. It is widely used in various industries, including e-commerce, finance, logistics, telecommunications, and the public sector. This tutorial will provide a comprehensive guide to help you get started with TD Database and explore its key features and functionalities.

Installation and Setup

To install TD Database, you can follow the official installation guide based on your operating system and environment. Once installed, you can start the database service using the command "./tdd start".

Creating a Database and Tables

To create a database, use the "CREATE DATABASE" statement. Tables can be created using the "CREATE TABLE" statement. For example:
CREATE DATABASE my_database;
CREATE TABLE users (
id INT PRIMARY KEY,
name VARCHAR(255),
email VARCHAR(255)
);

Inserting, Updating, and Deleting Data

Data can be inserted using the "INSERT INTO" statement. To update data, use the "UPDATE" statement. To delete data, use the "DELETE" statement. For example:
INSERT INTO users (id, name, email) VALUES (1, 'John Doe', 'john@');
UPDATE users SET name = 'Jane Doe' WHERE id = 1;
DELETE FROM users WHERE id = 1;

Querying Data

Data can be queried using the "SELECT" statement. The "WHERE" clause can be used to filter results. For example:
SELECT * FROM users;
SELECT * FROM users WHERE name LIKE '%Doe%';

Transactions

TD Database supports ACID transactions to ensure data consistency and integrity. To start a transaction, use the "BEGIN" statement. To commit the transaction, use the "COMMIT" statement. To rollback the transaction, use the "ROLLBACK" statement.

Concurrency Control

TD Database uses multi-version concurrency control (MVCC) to handle concurrent access to data. This allows multiple transactions to read and write data concurrently without blocking each other.

Data Partitioning

TD Database supports data partitioning to distribute data across multiple servers. This improves scalability and performance.

Replication

TD Database supports synchronous and asynchronous replication to ensure high availability and data redundancy.

Monitoring and Management

TD Database provides a comprehensive set of monitoring and management tools to track performance, identify bottlenecks, and manage the database.

Advantages of TD Database
