The Apache Spark adapter plugin for dbt

Project description

dbt logo

Unit Tests Badge

dbt enables data analysts and engineers to transform their data using the same practices that software engineers use to build applications.

dbt is the T in ELT. Organize, cleanse, denormalize, filter, rename, and pre-aggregate the raw data in your warehouse so that it's ready for analysis.


The dbt-spark package contains all of the code enabling dbt to work with Apache Spark and Databricks. For more information, consult the docs.

Getting started

Running locally

A docker-compose environment starts a Spark Thrift server and a Postgres database as a Hive Metastore backend. Note: dbt-spark now supports Spark 3.3.2.

The following command starts two docker containers:

docker-compose up -d

It will take a bit of time for the instance to start, you can check the logs of the two containers. If the instance doesn't start correctly, try the complete reset command listed below and then try start again.

Create a profile like this one:

  target: local
      type: spark
      method: thrift
      port: 10000
      user: dbt
      schema: analytics
      connect_retries: 5
      connect_timeout: 60
      retry_all: true

Connecting to the local spark instance:

  • The Spark UI should be available at http://localhost:4040/sqlserver/
  • The endpoint for SQL-based testing is at http://localhost:10000 and can be referenced with the Hive or Spark JDBC drivers using connection string jdbc:hive2://localhost:10000 and default credentials dbt:dbt

Note that the Hive metastore data is persisted under ./.hive-metastore/, and the Spark-produced data under ./.spark-warehouse/. To completely reset you environment run the following:

docker-compose down
rm -rf ./.hive-metastore/
rm -rf ./.spark-warehouse/
