BigQuery provides first-party assist for Delta Lake

Delta Lake has over 20M+ month-to-month downloads. BigQuery, now with first-party assist for Delta Lake, builds on Delta’s wealthy connector ecosystem and seamlessly integrates with Databricks. On this weblog, we are going to cowl:


  • Delta Lake on Google Cloud
  • Constructing an open information lakehouse with Databricks and BigQuery
  • Find out how to learn Delta Lake in BigQuery

Delta Lake on Google Cloud

Delta Lake is an optimized storage layer, enhancing efficiency and reliability for enterprise information lakes. Delta is utilized by over 10,000 firms, together with greater than 60% of the Fortune 500. As a totally open sourced Linux Basis challenge, Delta Lake affords a wealthy connector ecosystem with assist from many fashionable open supply frameworks and business engines. BigQuery now affords built-in Delta Lake assist, extending the Delta Lake ecosystem to Google Cloud. 


With BigQuery assist, you’ll be able to write Delta and proceed to entry Google Cloud native providers downstream, all from a single copy of knowledge. BigQuery’s Delta connector contains assist for latest Delta improvements comparable to deletion vectors, column mapping, and liquid clustering

Lakehouse on Databricks and BigQuery

The lakehouse structure combines the flexibleness of knowledge lakes with the reliability of knowledge warehouses. BigQuery assist for Delta Lake is enabled by BigLake. BigLake is a storage engine that allows prospects to retailer information in an open desk format on cloud object storage, offering the flexibleness to make use of BigQuery with different platforms like Databricks. Prospects can converge their information warehouses and information lakes on a unified storage layer, utilizing Delta Lake and BigLake.

By standardizing your information lake in Delta Lake, you’ll be able to:

  • Unify information entry: Preserve a single authoritative copy of your information that may be queried by each Databricks and BigQuery with out the necessity to export, copy, or use manifest information 
  • Effectively share information: Share information seamlessly throughout totally different processing engines like BigQuery, Databricks, Dataproc, and Dataflow, enabling environment friendly information utilization and collaboration

“Google Cloud is dedicated to fostering an open and interoperable information ecosystem,” stated Ritika Suri, Director, Knowledge and AI Know-how Partnerships at Google Cloud. “Including assist for Delta Lake in BigQuery is a testomony to our dedication to delivering an open platform with a complete set of cloud options for managing their information.”

Studying Delta Lake in BigQuery

You possibly can learn Delta Lake in BigQuery with only a few simple steps. To begin, let’s create a Delta desk in Databricks:

CREATE TABLE predominant.default.DeltaLake_demo

LOCATION 'gs://mybucket/mydata/mytable/'

AS (SELECT * FROM samples.nyctaxi.journeys );

Earlier than you’ll be able to entry the desk in BigQuery, you want a Cloud useful resource connection to Cloud Storage and the required permissions in BigQuery. You create a Delta Lake desk in BigQuery specifying the Delta Lake prefix because the URI:

CREATE EXTERNAL TABLE myProject.dataset.DeltaLake_demo

WITH CONNECTION `myProject.us.myConnection`


  format ="DELTA_LAKE",

  uris = ["gs://mybucket/mydata/mytable/"]


Once you question a Delta desk, BigQuery reads information beneath the prefix to determine the present model of the desk. BigQuery mechanically detects information and schema adjustments, so you’ll be able to learn the most recent snapshot with out manually refreshing desk metadata. 

SELECT * FROM myProject.dataset.DeltaLake_demo

Studying Delta Lake in BigQuery is that straightforward. With Delta Lake, you should utilize each Databricks and BigQuery with out duplicating information information or manually sustaining desk metadata, whereas additionally leveraging the most recent Delta options. 


At Databricks, we’re excited to allow open entry to enterprise information by Delta Lake. We are going to proceed to spend money on our partnership with Google Cloud to assist prospects combine Databricks with BigQuery and different Google Cloud providers. 


You possibly can study extra about Delta Lake and our partnership with Google Cloud at upcoming periods at Knowledge and AI Summit from June 10-13, 2024. Periods are stay in San Francisco and digital in a hybrid format.
