...配置解读
oriole 模板使用 OrioleDB 存储引擎，从根本上解决 PostgreSQL 表膨胀问题。
关键特性：
- 无膨胀设计：使用 UNDO 日志而非多版本并发控制 (MVCC)
- 无需 VACUUM：消除 autovacuum 带来的性能抖动
- 行级 WAL：更高效的日志记录和复制
- 压缩存储：内置数据压缩，减少存储空间
适用场景：
- 高频更新的 OLTP 工作负载
- 对写入延迟敏感的应用
- 需要稳定响应时间（消除 VACUUM 影响）
- 大表频繁更新导致膨胀的场景
使用方法：
-- 创建使用 OrioleDB 存储的表
CREATE TABLE orders (
id SERIAL PRIMARY KEY,
customer_id INT,
amount DECIMAL(10,2)
) USING orioledb;
-- 对现有表无法直接转换，需要重建
注意事项：
- OrioleDB 基于 PostgreSQL 17
- 需要将
orioledb添加到shared_preload_libraries - 部分 PostgreSQL 特性可能不完全支持
- 不支持 ARM64 架构
