hasura graphql-engine v1.0.0-alpha26 已经发布了,有好多新的变动,测试使用docker 环境,同时pg 数据库使用了citus
citus 是一个方便扩展的pg 数据库扩展解决方案,很不错。
环境准备
docker-compose && citus
version: '2.1'
services:
graphql-engine:
image: hasura/graphql-engine:v1.0.0-alpha26
ports:
- "8080:8080"
command: >
/bin/sh -c "
graphql-engine --database-url postgres://postgres@master/postgres serve --enable-console;
"
master:
container_name: "${COMPOSE_PROJECT_NAME:-citus}_master"
image: 'citusdata/citus:7.5.1'
ports: ["${MASTER_EXTERNAL_PORT:-5432}:5432"]
labels: ['com.citusdata.role=Master']
worker:
image: 'citusdata/citus:7.5.1'
labels: ['com.citusdata.role=Worker']
depends_on: { manager: { condition: service_healthy } }
manager:
container_name: "${COMPOSE_PROJECT_NAME:-citus}_manager"
image: 'citusdata/membership-manager:0.2.0'
volumes: ['/var/run/docker.sock:/var/run/docker.sock']
depends_on: { master: { condition: service_healthy } }

CREATE TABLE citus.platformuser (
id integer DEFAULT nextval('citus.platformuser_id_seq'::regclass) PRIMARY KEY,
platformtype text NOT NULL,
loginuser integer NOT NULL DEFAULT nextval('citus.platformuser_loginuser_seq'::regclass),
platformname text NOT NULL
);
-- Indices -------------------------------------------------------
CREATE UNIQUE INDEX platformuser_pkey ON citus.platformuser(id int4_ops);
新功能测试
query {
citus_userlogin(order_by:{id:asc}) {
id
username
userage
}
}
query {
citus_userlogin_aggregate {
aggregate {
max {
userage
}
}
}
}
说明
测试只是一部分,实际上还有预设值的,都比较简单,hasura graphql-engine 是越来越方便了,hasura 团队很给力,
对于开发来说太方便了
