Amidst challenging times, ScyllaDB presents a highly attractive option for enterprises striving to excel in data-driven business decisions! 🌟

Installing ScyllaDB 🚀

First, we’ll need to install ScyllaDB on your machine! Make sure you have the latest C++23 compiler and some necessary libraries. To simplify this process, we can use the frozen toolchain pre-configured Docker image, eliminating the need to manually configure various environments! 🎉

Updating Git Submodules

Before we begin, execute the following command to update the Git submodules. Submodules are like nested projects within a Git project and ensure that you’re using the latest components!

$ git submodule update --init --force --recursive

• The update command ensures all submodules are updated to the correct version.
• The --init flag indicates that it will set up submodules if they haven’t been initialized.
• The --force option forces the update, even if there are uncommitted changes locally.
• --recursive ensures that even submodules within submodules are updated.

Running the Configuration Script

Next, we will run the configuration script to start building ScyllaDB! Execute the following command:

$ ./tools/toolchain/dbuild ./configure.py

• Here, ./configure.py is used to detect the system environment and generate a suitable build configuration file.
• dbuild specifies that the build should be done in the Docker environment.

Building ScyllaDB with Ninja

Once the configuration is done, we will use the ninja build tool to complete the building process for ScyllaDB:

$ ./tools/toolchain/dbuild ninja build/release/scylla

• ninja is a small, efficient build system that will build the actual ScyllaDB based on the files generated in the previous step.
• build/release/scylla is the target path for the build output. 👷‍♂️

And there you have it, the ScyllaDB server has been built! 🎉

Running ScyllaDB 🏁

To start the ScyllaDB server, you can use the following command:

$ ./tools/toolchain/dbuild ./build/release/scylla --workdir tmp --smp 1 --developer-mode 1

• --workdir tmp specifies the directory where data files will be stored, with tmp chosen as a temporary directory.
• --smp 1 indicates that one CPU core will be used, which is suitable for development and testing environments.
• --developer-mode 1 disables performance-related checks, making it easier for development debugging.

Once started, your ScyllaDB server is now up and running! To see more runtime options, you can execute:

$ ./tools/toolchain/dbuild ./build/release/scylla --help

This will give you help information to adjust runtime parameters according to your needs. 📖

ScyllaDB API and Compatibility 🔗

ScyllaDB is compatible with Apache Cassandra and its API - CQL. This means that if you are already familiar with this API, you can easily switch to ScyllaDB! Additionally, ScyllaDB also supports the Amazon DynamoDB™ API, but it needs to be enabled manually. For more information, you can check the documentation for Alternator and Getting started with Alternator. 📚

Code Examples and Use Cases 💻

Let’s look at some simple code examples to help you better understand how to use ScyllaDB!

Connecting to ScyllaDB

First, create a connection to ScyllaDB with the following code:

// Import the ScyllaDB module for subsequent operations
const scylladb = require('scylladb');

// Create a client connection, specifying the entry point for ScyllaDB
const client = new scylladb.Client({
  contactPoints: ['127.0.0.1'], // Connect to local ScyllaDB
  localDataCenter: 'datacenter1' // Define the data center
});

// Execute a query to select records from the users table with matching id
client.execute('SELECT * FROM users WHERE id = ?', [userId])
  .then(result => console.log(result))  // Successfully output query results
  .catch(error => console.error(error)); // Output error message

• In this code, we first import the scylladb module using require.
• Using new scylladb.Client, we create a connection where contactPoints is the address of the ScyllaDB you want to connect to, and localDataCenter ensures compatibility with the data center.
• Then we use client.execute to execute a CQL query, which returns a Promise that can be handled with .then() and .catch() for results and errors.

Inserting Data into a Table

Use the following code to insert data into the users table:

// Sample code to insert data
INSERT INTO users (id, name, email) VALUES (uuid(), 'John Doe', 'john.doe@example.com');

• The INSERT INTO statement is used to add a new record to the users table.
• The uuid() function generates a unique identifier (id), ensuring that the user ID is unique.
• 'John Doe' and 'john.doe@example.com' are the name and email of the newly inserted user, ensuring that these match with the columns in the table for data integrity! 👏

With these steps, you should now be able to smoothly install and start using ScyllaDB! We hope this guide has been helpful to you! 💪
