Databricks SQL Release notes 2021

The following outlines the improvements and updates in Databricks SQL from January through December 2021.

December 15, 2021

• Databricks SQL is Generally Available. This marks a major milestone in providing you with the first lakehouse platform that unifies data, AI, and BI workloads in one place. With GA, you can expect the highest level of stability, support, and enterprise-readiness from Databricks for mission-critical workloads. Read the GA announcement blog to learn more.

• Alerts are now scheduled independently of queries. When you create a new alert and create a query, you are prompted to also create a schedule for the alert. If you had an existing alert, we’ve duplicated the schedule from the original query. This change also allows you to set alerts for both Run as Owner and Run as Viewer queries. Run as Owner queries run on the designated alert schedule with the query owner’s credential. Run as Viewer queries run on the designated alert schedule with the alert creator’s credential. See What are Databricks SQL alerts? and Schedule a query.

• You can now re-order parameters in both the SQL editor and in dashboards.

• The documentation for creating heatmap visualizations has been expanded. See Heatmap options.

December 9, 2021

• When you create a table visualization, you can now set the font color for a column to a static value or a range of values based on the column’s field’s values. The literal value is compared to the threshold. For example, to colorize results whose values exceed 500000, create the threshold > 500000, rather than > 500,000. See Conditionally format column colors.

• Icons in the tabbed SQL editor schema browser now allow you to distinguish between tables and views.

December 1,2021

• You can now apply SQL configuration parameters at the workspace level. Those parameters automatically apply to all existing and new SQL endpoints in the workspace. See Configure SQL parameters.

November 18, 2021

• You can now open the SQL editor by using a sidebar shortcut. To open the SQL editor, click SQL Editor.

• If you have permission to create Data Science & Engineering clusters, you can now create SQL endpoints by clicking Create in the sidebar and clicking SQL Endpoint.

• Administrators can now transfer ownership of a query, dashboard, or alert to a different user via the UI. See:

• Transfer ownership of a query

• Transfer ownership of a legacy dashboard

• Transfer ownership of an alert

November 4, 2021

• In a Map (Choropleth) visualization visualization, the maximum number of gradient steps for colors in the legend has been increased from 11 to 20. The default is 5 gradient steps inclusive of Min color and Max color.

• The tabbed SQL editor now supports bulk tab management. If you right-click on a tab, you’ll see the option to Close others, Close left, Close right, and Close all. Note that if you right-click on the first or last tab, you won’t see the options to Close left or Close right.

October 28, 2021

• When you view a table in Catalog Explorer, you have two options to simplify interacting with the table:

• Click Create > Query to create a query that selects all columns and returns the first 1000 rows.

• Click Create > Quick Dashboard to open a configuration page where you can select columns of interest and create a dashboard and supporting queries that provide some basic information using those columns and showcase dashboard-level parameters and other capabilities.

October 19, 2021

• New keyboard shortcuts are now available in the tabbed editor:

• Open new tab:

  • Windows: Cmd+Alt+T

  • Mac: Cmd+Option+T

• Close current tab

  • Windows: Cmd+Alt+W

  • Mac: Cmd+Option+W

• Open query dialog

  • Windows: Cmd+Alt+O

  • Mac: Cmd+Option+O

September 23, 2021

• You can now create a new dashboard by cloning an existing dashboard, as long as you have the CAN RUN, CAN EDIT and CAN MANAGE permission on the dashboard and all upstream queries. See Clone a legacy dashboard.

• You can now use GROUP BY in a visualization with multiple Y-axis columns. See Scatter chart.

• You can now use {{ @@yPercent}} to format data labels in an unnormalized stacked bar chart. See Bar chart.

• If you use SAML authentication and your SAML credential will expire within a few minutes, you are now proactively prompted to log in again before executing a query or refreshing a dashboard. This helps to prevent disruption due to a credential that expires during query execution.

September 20, 2021

• You can now transfer ownership of dashboards, queries, and alerts using the Permissions REST API. See Query ACLs.

September 16, 2021

• In query results, BIGINT results are now serialized as strings when greater than 9007199254740991. This fixes a problem where BIGINT results could be truncated in query results. Other integer results are still serialized as numbers. Number formatting on axis labels and tooltips does not apply to BIGINT results that are serialized as strings. For more information about data types in Databricks SQL, see BIGINT type.

September 7, 2021

Databricks is rolling out the changes that follow over the course of a week. Your workspace may not be enabled for these changes until after September 7.

• Databricks SQL is now in Public Preview and enabled for all users in new workspaces.

Note

If your workspace was enabled for Databricks SQL during the Public Preview—that is, before the week beginning September 7, 2021—users retain the entitlement assigned before that date, unless you change it. In other words, if a user did not have access to Databricks SQL during the Public Preview, they will not have it now unless an administrator gives it to them.

• Administrators can manage which users have access to Databricks SQL by assigning the Databricks SQL access entitlement (databricks-sql-access in the API) to users or groups. By default, new users have this entitlement.

Administrators can limit a user or group to accessing only Databricks SQL and prevent them from accessing Data Science & Engineering or Databricks Mosaic AI by removing the Workspace Access entitlement (workspace-access in the API) from the user or group. By default, new users have this entitlement.

Important

To log in and access Databricks, a user must have either the Databricks SQL access or Workspace access entitlement (or both).

• A small classic SQL endpoint called Starter Endpoint is pre-configured on all workspaces, so you can get started creating dashboards, visualizations, and queries right away. To handle more complex workloads, you can easily increase its size (to reduce latency) or the number of underlying clusters (to handle more concurrent users). To manage costs, the starter endpoint is configured to terminate after 120 minutes idle.

September 2, 2021

• Users with the CAN EDIT permission on a dashboard can now manage the dashboard’s refresh schedule and subscription list. Previously, the CAN MANAGE permission was required. For more information, see Automatically refresh a dashboard.

• By default, visualizations no longer dynamically resize based on the number of results returned, but maintain the same height regardless of the number of results. To return to the previous behavior and configure a visualization to dynamically resize, enable Dynamically resize panel height in the visualization’s settings in the dashboard. For more information, see Table options.

• If you have access to more than one workspace in the same account, you can switch workspaces from within Databricks SQL. Click in the lower left corner of your Databricks workspace, then select a workspace to switch to it.

July 01, 2021

• The new Catalog Explorer allows you to easily explore and manage permissions on databases and tables. Users can view schema details, preview sample data, and see table details and properties. Administrators can view and change data object owners, and data object owners can grant and revoke permissions. For details, see What is Catalog Explorer?.

• Y-axes in horizontal charts have been updated to reflect the same ordering as in tables. If you have previously selected reverse ordering, you can use the Reverse Order toggle on the Y-axis tab to reverse the new ordering.

June 23, 2021

June 17, 2021

• Photon, Databricks’ new vectorized execution engine, is now on by default for newly created SQL endpoints (both UI and REST API). Photon transparently speeds up

  • Writes to Parquet and Delta tables.

  • Many SQL queries. See Limitations.

• Easily manage users and groups with CREATE GROUP, DROP GROUP, ALTER GROUP, SHOW GROUPS, and SHOW USERS commands. For details, see Security statements and Show statements.

• The query editor schema browser is snappier and faster on schemas with more than 100 tables. On such schemas, the schema browser will not load all columns automatically; the list of tables still shows as usual, but columns load only when you click a table. This change affects query autocomplete in the query editor, because it depends on this information to show suggestions. Until you expand a table and load its columns, those suggestions are not available.

June 03, 2021

• Admins of newly enabled Databricks workspaces now receive the Databricks SQL entitlement by default and are no longer required to give themselves the Databricks SQL access entitlement using the admin console.

• Photon is now in public preview and enabled by default for new SQL endpoints.

• Multi-cluster load balancing is now in public preview.

• You can now enable collaboration on dashboards and queries with other members of your organization using CAN EDIT permission. See Access control lists.

May 26, 2021

• SQL Analytics is renamed to Databricks SQL. This change has the following customer-facing impacts:

  • References in the web UI have been updated.

  • The entitlement to grant access to Databricks SQL has been renamed:

    • UI: Databricks SQL access (previously SQL Analytics access)

    • SCIM API: databricks-sql-access (previously sql-analytics-access)

    Users, groups, and service principals with the previous entitlement have been migrated to the new entitlement.

  • Tags for audit log events related to Databricks SQL have changed:

    • The prefix for Databricks SQL events is now databrickssql.

    • changeSqlAnalyticsAcl is now changeDatabricksSqlAcl.

• Dashboard updates

May 13, 2021

• Databricks SQL no longer tries to guess column types. Previously, a column with the format xxxx-yy-dd was automatically treated as a date, even if it was an identification code. Now that column is no longer automatically treated as a date. You must specify that in the query if so desired. This change may cause some visualizations that relied on the previous behavior to no longer work. In this release, you can change > Settings > Backwards Compatibility option to return to the previous behavior. In a future release we will remove that capability.

• The query editor now has a query progress indicator. State changes are now visible in a continually updated progress bar.
