While it is possible to create tables on Databricks that don’t use Delta Lake, those tables don’t provide the transactional guarantees or optimized performance of Delta tables. For more information about other table types that use formats other than Delta Lake, seeWhat is a table?. ...
Azure Databricks Delta Lake tables do not support stored procedures in the traditional sense. However, you can use Databricks notebooks to create reusable code that can be used to perform operations on Delta tables. For more details, refer to Converting Stored Procedures to Databricks. Hope ...
.saveAsTable("delta_merge_into") Then merge a DataFrame into the Delta table to create a table calledupdate: %scala val updatesTableName = "update" val targetTableName = "delta_merge_into" val updates = spark.range(100).withColumn("id", (rand() * 30000000 * 2).cast(IntegerType)) ...
table. In Databricks Runtime 11.3 LTS and below, Delta Lake features were enabled in bundles calledprotocol versions. Table features are the successor to protocol versions and are designed with the goal of improved flexibility for clients that read and write Delta Lake. SeeWhat is a protocol ...

In this example, there is acustomerstable, which is an existing Delta table. It has an address column with missing values. The updated data exists in Parquet format. Create aDataFramefrom the Parquet file using an Apache Spark API statement: ...

And choose a table within this share: Step 3. Query Databricks Data from Oracle ADB. You’ll now see a new external table in the Oracle database. You can run a query on it: Keep in mind, the Oracle ADB external table is connected to the Delta Server endpoint: Copy code snippet...
This book shows you how to use Apache Spark, Delta Lake, and Databricks to build data pipelines, manage and transform data, optimize performance, and more. Additionally, you’ll implement DataOps and DevOps practices, and orchestrate data workflows.IntroductionDatabricks Unity Catalog allows you to...
spark.conf.set("spark.sql.shuffle.partitions","64")#Proportionate to number of cores State operators:These are where the state gets stored after being aggregated. It allows the pipeline to keep a context of what has come before without having to create a table for it. We current...
