Databricks and Delta Lake Tables

Databricks and Delta Lake Tables

Mappings can access managed and unmanaged Databricks tables.
Mappings can access managed Databricks tables, including Delta Lake tables. Delta Lake is a data lake resource that stores data in large tables. Databricks uses proprietary Delta software to manage stored data and allow fast access to the data. Delta Lake supports ACID transactions.
Mappings can also access unmanaged Databricks tables built on top of any of the following storage types:
  • Azure blob storage
  • Azure Data Lake Storage (ADLS) Gen1 or Gen2
  • Amazon Web Services (AWS) S3
For more information, see the Databricks documentation.
You can configure dynamic mappings to apply Databricks source schema changes to Delta Lake targets. See Databricks Schema Evolution.
To use Delta Lake resources in a mapping, create a relational data object and use a JDBC connection to connect to the resource.
