This guide shows you how to import data from GCP (Google Cloud Platform).

Google Cloud Storage

You can enable the Google Cloud Storage using the plugin pinot-gcs. In the controller or server, add the config -

-Dplugins.dir=/opt/pinot/plugins -Dplugins.include=pinot-gcs

{% hint style="info" %} By default Pinot loads all the plugins, so you can just drop this plugin there. Also, if you specify -Dplugins.include, you need to put all the plugins you want to use, e.g. pinot-json, pinot-avro , pinot-kafka-2.0... {% endhint %}

GCP filesystems provides the following options -

  • projectId - The name of the Google Cloud Platform project under which you have created your storage bucket.
  • gcpKey - Location of the json file containing GCP keys. You can refer Creating and managing service account keys to download the keys.

Each of these properties should be prefixed by pinot.[node].storage.factory.class.gs. where node is either controller or server depending on the config

e.g.

pinot.controller.storage.factory.class.gs.projectId=test-project
