Explanation

The oriole template uses OrioleDB storage engine, fundamentally solving PostgreSQL table bloat problems.

Key Features:

Bloat-free Design: Uses UNDO logs instead of Multi-Version Concurrency Control (MVCC)
No VACUUM Required: Eliminates performance jitter from autovacuum
Row-level WAL: More efficient logging and replication
Compressed Storage: Built-in data compression, reduces storage space

Use Cases:

High-frequency update OLTP workloads
Applications sensitive to write latency
Need for stable response times (eliminates VACUUM impact)
Large tables with frequent updates causing bloat

Usage:

-- Create table using OrioleDB storage
CREATE TABLE orders (
    id SERIAL PRIMARY KEY,
    customer_id INT,
    amount DECIMAL(10,2)
) USING orioledb;

-- Existing tables cannot be directly converted, need to be rebuilt

Notes:

OrioleDB supports PostgreSQL 16, 17, and 18; the template defaults to PG18, and you can select a major version with -v 16, -v 17, or -v 18
Need to add orioledb to shared_preload_libraries
Some PostgreSQL features may not be fully supported
Use the matching OrioleDB packages for the selected PostgreSQL major and OS architecture
