Support for multiple programming languages: Azure Synapse is compatible with various languages like Python, Java, SQL, and Spark SQL, making it more accessible to a broader range of users.
What Is Databricks?
Databricks is a lakehouse platform with the best qualities of a data lake and warehouse to produce a cost-effective data management and governance solution. As a result, Databricks helps organizations build a single, continuous data system instead of managing multiple data architectures simultaneously. In addition, Databricks uses Delta Lake architecture, an open-source storage format, to confer data governance, reliability, and ACID-compliance transactions on a data lake.
Databricks at a Glance
The following features characterize Databricks:
Open: Databricks is built using Delta Lake, which uses the Parquet open-source storage format, making it flexible and platform-agnostic for integrating multiple cloud or on-premises platforms.
Simplified governance: Databricks has a unified, single architecture that uses the best data warehouses and data lake features. This streamlined architecture means reduced data governance workloads instead of the multiple workloads required for maintaining the data warehouse and data lake different architectures simultaneously.
Reliable data management: The various upstream and downstream processes involved with ELT/ETL movement among multiple architectures create more room for errors, reducing data quality and integrity and increasing management costs and time. However, the continuous architecture employed by Databricks reduces such movement, reducing the risk of errors/bugs and significantly reducing workload costs.

Key Distinctions: Features, Architecture, and Integrations
Azure Synapse utilizes a 3-component architecture; Data storage, processing, and visualization in a single, unified platform. On the other hand, Databricks utilizes a lakehouse architecture that enables the best data warehouse and data lake features into one continuous platform.
Availability and Pricing
Azure synapse utilizes a PAYG option where users are charged based on the resources used. These resources vary depending on the level of data exploration, warehousing, Spark pool, integration, and storage needs, like the number of TBs stored and processed, data movement, runtime, and cores used in data flow execution and debugging. The number of parameters used to determine your Azure Synapse analytics is large and can be complex. However, organizations can estimate their billing costs thanks to the Azure pricing calculator.
For Databricks, a free plan is available but comes with limited features. Databricks also uses a PAYG pricing based on usage costs and charges per second using Databricks Unit (DBU). Organizations can get sizeable discounts when they commit to a specific usage level. A single DBU depends on workload factors like the amount of processed data, memory, vCPU power, region, and Databricks services used.
Most ML environments rely on versioning systems like Git to collaborate effectively to create a seamless workflow.
