SurrealDB is a cloud-native NoSQL database that provides high availability, scalability, and low latency. It is designed to handle large-scale, mission-critical workloads and offers features such as automatic sharding, backup and restore, and point-in-time recovery. In this tutorial, we will cover the basic concepts of SurrealDB and how to use it.
Getting Started
To get started with SurrealDB, you will first need to sign up for an account on the SurrealDB website. Once you have signed up, you can create a new database cluster from the dashboard. A cluster is a group of servers that work together to provide a single, highly available database service.
Creating a Database
To create a new database, navigate to the “Databases” section of the SurrealDB dashboard and click the “Create Database” button. You will be prompted to enter a name for the database, select a cluster to host the database, and choose the desired configuration options, such as the number of nodes, storage capacity, and replication factor.
Connecting to a Database
SurrealDB supports a variety of APIs and drivers for connecting to a database, including Java, Python, Node.js, and more. To connect to a database, you will need to obtain the connection string and authentication credentials from the SurrealDB dashboard. You can then use these credentials to connect to the database from your application code.
Data Modeling
SurrealDB is a NoSQL database, which means that it does not use a fixed schema to store data. Instead, you can store data in a flexible, schema-less format, such as JSON, BSON, or other similar formats. This makes it easy to store and retrieve data without having to worry about the schema.
CRUD Operations
SurrealDB supports basic CRUD (Create, Read, Update, Delete) operations for working with data. You can create new documents in a collection using the insert command, retrieve documents using the find command, update documents using the update command, and delete documents using the delete command.
Conclusion
SurrealDB is a powerful NoSQL database that offers high availability, scalability, and low latency for mission-critical workloads. With its flexible data modeling, easy-to-use APIs, and robust feature set, SurrealDB is a great choice for any application that needs to store and retrieve large amounts of data.
