pgspider 其他扩展的集成

Posted 2021-03-12 rongfengliang

目前的测试，pgspider 对于pg 的侵入不大，很多已有的pg扩展都是可以使用的，所以基于比较常用的
添加了mongdb，sql server 等的容器镜像，构建比较简单，都是基于现有构建的base

参考使用

暂时没有sql server 的而且docker 镜像偏大，暂时没测试

• mongodb

// 启用扩展

CREATE EXTENSION mongo_fdw;

CREATE EXTENSION pgspider_core_fdw;

CREATE EXTENSION postgres_fdw;

CREATE EXTENSION pgspider_fdw;

CREATE SERVER parent FOREIGN DATA WRAPPER pgspider_core_fdw OPTIONS (host ‘127.0.0.1‘, port ‘5432‘);

CREATE SERVER mongo_server FOREIGN DATA WRAPPER mongo_fdw OPTIONS (address ‘mongo‘, port ‘27017‘, authentication_database ‘admin‘);

CREATE USER MAPPING FOR postgres SERVER mongo_server OPTIONS(username ‘dalong‘, password ‘dalong‘);

CREATE FOREIGN TABLE userapps(_id NAME,appid int,appname text,__spd_url text) SERVER parent;

CREATE FOREIGN TABLE userapps__mongo_server__0(_id NAME,appid int,appname text) SERVER mongo_server OPTIONS (database ‘apps‘, collection ‘userapps‘);

select * from userapps;

mongodb docs:

{

    "_id" : ObjectId("5e3a782b132f94cefe1d1e60"),

    "appname" : "demoapp",

    "appid" : 1

}
