PostgreSQL adapter for Ductr ETL

This gem provides useful controls to operate Ductr with PostgreSQL databases.

Installation

Add this line to your application's Gemfile:

gem 'ductr-postgres'

And then execute:

$ bundle install

Require ductr/postgres in the config/app.rb file:

require "ductr/postgres"

Usage

You can now use the adapter in your YAML configuration:

adapters:
  some_postgres_database:
    adapter: postgres
    host: localhost
    user: postgres
    password: s3cr3t
    database: example

You can pass any option recognized by sequel. See the Sequel Sequel general options list for further details. See the Sequel PostgreSQL specific options list for further details.

The configured adapter can now be used in Ductr jobs e.g.:

source :some_postgres_database, :streamed
def select_some_stuff(db, offset, limit)
  db[:items].offset(offset).limit(limit)
end
