This guide shows you how to import data from files stored in Azure Data Lake Storage (ADLS)

Azure Data Lake Storage

You can enable the Azure Data Lake Storage using the plugin pinot-adls. In the controller or server, add the config -

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

{% 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 %}

Azure Blob Storage provides the following options -

  • accountName : Name of the azure account under which the storage is created
  • accessKey : access key required for the authentication
  • fileSystemName - name of the filesystem to use i.e. container name (container name is similar to bucket name in S3)
  • enableChecksum - enable MD5 checksum for verification. Default is false.

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

e.g.

pinot.controller.storage.factory.class.adl.accountName=test-user
