使用 WiltonDB / Babelfish 的 Microsoft SQL Server 兼容内核替代 PostgreSQL
Categories:
ivory
配置模板基于 full
模板,使用使用瀚高的 IvorySQL (Oracle兼容内核)替代原生 PostgreSQL 内核
完整教程请参考:IvorySQL (Oracle兼容) 内核使用说明
配置概览
- 配置名称:
ivory
- 节点数量: 四节点
- 配置说明:Babelfish/WiltonDB 四节点配置模板,提供 Microsoft SQL Server 兼容能力
- 适用系统:
el7
,el8
,el9
,u20
,u22
,u24
- 适用架构:
x86_64
,aarch64
(el7
除外) - 相关配置:
full
- Vagrant:四节点
pigsty/vagrant/spec/full.rb
启用方式:在 configure
过程中使用 -c ivory
参数:

注意事项
请注意,IvorySQL 仅在 EL 7/8/9 上可用,目前 EL7 因为过保,官方已经不再提供支持。
IvorySQL 提供 x86_64
(amd64) 与 aarch64
(arm64) 的 RPM 包,但 EL7 不提供 aarch64
架构的支持。
请注意,IvorySQL 目前版本兼容 PostgreSQL 16 大版本。
