Dimension tables do well with Dual storage mode. Dual mode lets you use cached data or live queries. This helps you use resources in a smart way. You should use the Databricks SQL engine when building models. This engine makes your queries run better and can handle lots of data.

Best Practice

Description

Use DirectQuery for fact tables

This mode allows you to submit queries directly to Databricks SQL, enhancing performance.

Use Dual storage mode for dimension tables

Dual mode lets you choose between cached data and querying the source, optimizing efficiency.

Leverage Databricks SQL engine

Using this engine improves SQL query generation and scalability, ensuring optimal performance.

Tip: Choose the best storage mode for each table. This makes your reports faster and keeps your data up-to-date.

Security Management

You need to keep your data safe at every step. Security starts at the OneLake layer and goes through workspaces and Lakehouses. Workspace security lets you control who can see and use your data. Role-based access control makes sure only the right people get in. You can set permissions for each schema or table. This keeps private data safe. Governance policies help you follow rules and protect your data.

Aspect

Description

Role-Based Access Control

Ensures only authorized users can access specific datasets.

Permissions Management

Allows setting permissions for lakehouse schemas or tables, limiting access to sensitive data.

Governance Policies

Establishes rules to protect sensitive data and ensure compliance with regulations.

Note: Always check permissions and update them when people change jobs or leave.

Performance Tuning

You can make your reports faster by doing a few things. First, clean up your data model. Remove columns and tables you do not need. Next, use the right storage modes and aggregations. Aggregations help you sum up data and speed up questions. Make your DAX measures work fast and well. Set up incremental refresh to update only new data.

  1. Clean up your data model

  2. Use the right storage modes and aggregations

  3. Make DAX measures faster

  4. Set up incremental refresh

Efficient data refresh keeps your data current without slowing things down. You can use schedules, adjust how many things run at once, and make your source queries better for the best results.
