pgspider zombodb集成使用

zombodb 是一个强大的pg 扩展，我们可以像操作数据库一样操作es，以下是pgspider 与zombodb 的构建

说明，使用最新版本v5.6.16-1.0.20 构建失败，使用了v.40

dockerfile

老样子基于已经构建好的pgspider base 镜像

集成plv8 的版本

FROM dalongrong/pgspider:zombodb

RUN apt-get update && apt-get install -y libc++1

COPY --from=dalongrong/pgspider:plv8 /usr/local/pgspider/lib/postgresql/plv8-2.3.12.so /usr/local/pgspider/lib/postgresql/plv8-2.3.12.so

COPY --from=dalongrong/pgspider:plv8 /usr/local/pgspider/share/postgresql/extension /usr/local/pgspider/share/postgresql/extension

使用

• docker-compose 文件

version: "3"

services: 

  pg-zombodb:

    image: dalongrong/pgspider:zombodb-plv8

    ports:

    - "5432:5432"

    environment: 

    - "POSTGRES_PASSWORD=dalong"

  elasticsearch:

    image: elasticsearch:6.6.0

    ports: 

    - "9200:9200"

    environment:

      - http.host=0.0.0.0

      - transport.host=0.0.0.0

      - network.host=0.0.0.0

      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"

• 创建扩展

CREATE EXTENSION zombodb;

CREATE TABLE products (

  id SERIAL8 NOT NULL PRIMARY KEY,

  name text NOT NULL,

  keywords varchar(64)[],

  short_summary text,

  long_description zdb.fulltext, 

  price bigint,

  inventory_count integer,

  discontinued boolean default false,

  availability_date date

);

CREATE INDEX idxproducts 

                   ON products 

                USING zombodb ((products.*))

                 WITH (url=‘http://elasticsearch:9200/‘);

INSERT INTO "public"."products"("id","name","keywords","short_summary","long_description","price","inventory_count","discontinued","availability_date")

VALUES

(1,E‘Magical Widget‘,E‘{magical,widget,round}‘,E‘A widget that is quite magical‘,E‘Magical Widgets come from the land of Magicville and are capable of things you can\‘t imagine‘,9900,42,FALSE,E‘2015-08-31‘),

(2,E‘Baseball‘,E‘{baseball,sports,round}‘,E‘It\‘s a baseball‘,E‘Throw it at a person with a big wooden stick and hope they don\‘t hit it‘,1249,2,FALSE,E‘2015-08-21‘),

(3,E‘Telephone‘,E‘{communication,primitive,"alexander graham bell"}‘,E‘A device to enable long-distance communications‘,E‘Use this to call your friends and family and be annoyed by telemarketers. Long-distance charges may apply‘,1899,200,FALSE,E‘2015-08-11‘),

(4,E‘Box‘,E‘{wooden,box,"negative space",square}‘,E‘Just an empty box made of wood‘,E‘A wooden container that will eventually rot away. Put stuff it in (but not a cat).‘,17000,0,TRUE,E‘2015-07-01‘);

SELECT * FROM products WHERE products ==> ‘sports box‘;
