Welcome to the world of OrioleDB, a modern cloud-native storage engine designed to enhance the PostgreSQL database experience. This guide will take you step-by-step through the installation and usage of OrioleDB, all while ensuring that your journey is smooth and effective.

What is OrioleDB?

OrioleDB is an innovative storage engine that builds upon PostgreSQL’s foundational strengths. It aims to overcome some of the existing challenges in PostgreSQL and optimize it for modern hardware and cloud environments. With features designed for contemporary needs, OrioleDB ensures enhanced performance, reduced maintenance, and a more efficient database experience.

Key Features of OrioleDB

• No legacy CPU bottlenecks – Optimized for modern multi-core processors.
• Reduced maintenance through concepts like undo logs and page-merging.
• Distributed architecture with row-level write-ahead logging.
• Removes the need for buffer mapping with lock-less page reading.
• Eliminates bloat through MVCC based on the UNDO log concept.
• Utilizes copy-on-write checkpoints for consistent data snapshots.

Installation Process

To get started with OrioleDB, you can either use a Docker container or build it from source. Below, we outline both methods.

Using Docker Container

To use OrioleDB as a Docker container, follow these steps:

docker pull orioledborioledb:latest-pg16

To start the container similarly to a PostgreSQL server, use the following command:

docker run --name some-postgres -e POSTGRES_PASSWORD=... -e POSTGRES_INITDB_ARGS=--locale=C -d -p5432:5432 orioledborioledb:latest-pg16

Make sure to set the default locale to C, POSIX, or use the ICU locale. For more details, check out our Docker Hub.

Building from Source

If you prefer to build OrioleDB from source, ensure you have the following dependencies:

• PostgreSQL with extensibility patches
• Development package for libzstd
• Python 3.5+ with the testgres package

Once you’ve fulfilled the requirements, follow these commands:

git clone https://github.com/orioledb/orioledb
cd orioledb
make USE_PGXS=1
make USE_PGXS=1 install
make USE_PGXS=1 installcheck

After installation, add the following line to your postgresql.conf file and restart the PostgreSQL server:

shared_preload_libraries = orioledb.so

Setting Up OrioleDB

Once OrioleDB is installed and running, you need to enable it in your database:

CREATE EXTENSION orioledb;

Now you can create tables using OrioleDB:

CREATE TABLE table_name (...) USING orioledb;

Troubleshooting

If you run into any issues during installation or usage, consider the following troubleshooting tips:

• Ensure all dependencies are installed and updated to the required versions.
• Check that your PostgreSQL configuration file has the proper settings.
• Make sure to use the correct locale settings when launching Docker containers or creating databases.
• For best practices and further details, visit our documentation at Docker Hub.
• If problems persist, don’t hesitate to reach out for support and advice. For more insights, updates, or to collaborate on AI development projects, stay connected with fxis.ai.
