Apache Ignite 3 is a powerful distributed database designed for high-performance computing. Whether you’re a seasoned developer or just starting out, this guide will walk you through the steps to get started with Ignite, from installation to running SQL commands. Let’s dive in!

Step 1: Downloading Apache Ignite

To begin, you’ll need to download the latest release. Follow these simple steps:

• Visit the Ignite web page.
• Scroll down and look for the Binary releases section.
• Click on the link to download the current latest release zip archive.

Step 2: Installing Apache Ignite

Once the zip archive is downloaded, you’re ready to set up Ignite. Run the following command in your terminal:

shell
https://dlcdn.apache.org/ignite/3.0.0-beta1/ignite3-3.0.0-beta1.zip

Unzip the downloaded file:

shell
unzip ignite3-3.0.0-beta1.zip

After unzipping, you will have two directories: ignite3-db-3.0.0-version and ignite3-cli-3.0.0-version.

Step 3: Starting Ignite Node

Navigate to the database directory and start your Ignite node:

shell
cd ignite3-db-3.0.0-beta1/bin
ignite3db start

This will start your Ignite node with the name defaultNode. You can customize the node configuration by editing etc/ignite-config.conf before starting.

Step 4: Connecting to Your Node Using Ignite CLI

To connect to your node, go to the Ignite CLI directory:

shell
cd ../ignite3-cli-3.0.0-beta1/bin
ignite3

Initialize a simple cluster by running:

shell
cluster init --name myCluster --cmg-node defaultNode --meta-storage-node defaultNode

Now you can switch the CLI to SQL interactive mode using:

shell
sql

In SQL mode, you can execute SQL commands. Here’s a quick example:

sql
CREATE TABLE IF NOT EXISTS Person (id int primary key, city varchar, name varchar, age int, company varchar);
INSERT INTO Person (id, city, name, age, company) VALUES (1, 'London', 'John Doe', 42, 'Apache');
SELECT * FROM Person;

Step 5: Building Apache Ignite from Source

If you prefer to build Ignite from source, it’s quite easy with Gradle. Run the following command:

shell
./gradlew clean distZip

Your build artifacts will be located in the packagingdb and packagingcli directories.

Step 6: Running Ignite with Docker

If Docker is your forte, you can spin up Ignite using Docker commands:

shell
./gradlew docker
cd packaging
docker compose up -d

To run the CLI within Docker, you can use:

shell
docker run -it --rm --net ignite3_default apacheigniteignite3 cli connect http://node1:10300

Troubleshooting

If you encounter any issues during installation or setup, consider these troubleshooting tips:

• Ensure that Java is installed and configured properly on your machine.
• Double-check that you have the right permissions to access the necessary files and directories.
• Look into the configuration files for any missing parameters or errors in settings.
