Pinot Adapter

Ruby on Rails Active Record database adapter for Apache Pinot, a client library for Pinot-compatible database servers.

Disclaimer: This is alpha stage software, please use with caution.

Installation

Install the gem and add to the application's Gemfile by executing:

$ bundle add activerecord-pinot-adapter

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install activerecord-pinot-adapter

This adapter uses the pinot gem, that is the Apache Pinot client, you can install an specific version of the client, but it's highly recommended to let this gem manage its own dependency.

Usage

TODO: Write usage instructions here First step is to configure the config/database.yml

pinot:
  adapter: pinot
  host: host.to.your.broker.com
  port: 443
  controller_host: host.to.your.controller.com
  controller_port: 443
  protocol: https

Adapter also supports:

• socks5_uri in case you are using are using a jump host as your socks proxy. Please provide the full uri with protocol and port (eg. socks5://127.0.0.1:8080)
• bearer_token in case your broker/host need a bearer token to authenticate the requests
• query_options in case needs to specify pinot query options, it's a hash, and keys are on the underscore format.

By design we avoided trying to guess the port and protocol based on any provided information, so port is always required, and protocol by default is http to make easier to test local, and then must be specified as https for production.

Models

To start using on your application, it's recommended to create an abstract class, so it's only needed to specify the connection database in one place.

class PinotRecord < ApplicationRecord
  self.abstract_class = true
  connects_to database: {writing: :pinot, reading: :pinot}
end

After abstract class, just use it on any class you want to use.

class MyModel < PinotRecord
end

If you are incrementally migrating from one database to Pinot, or want to use both in parallel, prefix your models on a namespace, and use self.table_name= to specify the correct table name for the model.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
