Apache Ignite is a distributed database for high-performance computing with in-memory speed.

Ignite 3 is the next generation of the platform that will support a modernized modular architecture, along with improved usability and developer experience.

The current alpha version includes the following features:

• Unified CLI tool
• New configuration engine
• New schema management engine
• Table API
• Atomic storage implementation based on Raft
• New SQL engine based on Apache Calcite and JDBC driver
• New binary client protocol and its implementation in Java

Installation

1. Download Ignite 3 Alpha 5:

   curl -L "https://www.apache.org/dyn/mirrors/mirrors.cgi?action=download&filename=ignite/3.0.0-alpha5/apache-ignite-3.0.0-alpha5.zip" -o apache-ignite-3.0.0-alpha5.zip
   

2. Unzip the downloaded file:

   unzip apache-ignite-3.0.0-alpha5.zip && cd apache-ignite-3.0.0-alpha5
   

3. Add your installation directory to the PATH environment variable:

   echo 'export IGNITE_HOME="'`pwd`'"' >> ~/.bash_profile && echo 'export PATH="$IGNITE_HOME:$PATH"' >> ~/.bash_profile && source ~/.bash_profile
   

4. (optional) If you start the cluster locally then install the core artifacts:

   ignite bootstrap
   

Running Examples

Examples are shipped as a separate Maven project, which is located in the examples folder. To start running you simply need to import provided pom.xml file into your favourite IDE.

The following examples are included:

• RecordViewExample - demonstrates the usage of the org.apache.ignite.table.RecordView API
• KeyValueViewExample - demonstrates the usage of the org.apache.ignite.table.KeyValueView API
• SqlJdbcExample - demonstrates the usage of the Apache Ignite JDBC driver.
• SqlApiExample - demonstrates the usage of the Java API for SQL.
• VolatilePageMemoryStorageExample - demonstrates the usage of the PageMemory storage engine configured with an in-memory data region.
• PersistentPageMemoryStorageExample - demonstrates the usage of the PageMemory storage engine configured with a persistent data region.

To run any other example, do the following:

1. Import the examples project into your IDE.
2. Start a server node using the CLI tool:

   ignite node start --config=$IGNITE_HOME/examples/config/ignite-config.json my-first-node
   

3. (optional) If the cluster is not initialized then initialize the cluster:

   ignite cluster init --cluster-name=ignite-cluster --node-endpoint=localhost:10300 --meta-storage-node=my-first-node
   

4. Run the preferred example in the IDE.

Using CLI

Alpha 5 leverages the advantage of using the CLI for the development. Updated CLI ships the following features:

• Bash auto-completions. If you are using bash/zsh you can hit the TAB during typing ignite commands.
• Interactive mode. Enter the interactive by running ignite without arguments.
• SQL REPL. Run SQL queries right from your terminal with ignite sql command.
