Databricks SQL release notes

This article lists new Databricks SQL features and improvements, along with known issues and FAQs.

Release process

Databricks releases updates to the Databricks SQL web application user interface on an ongoing basis, with all users getting the same updates rolled out over a short period of time.

In addition, Databricks typically releases new SQL warehouse compute versions regularly. Two channels are always available: Preview and Current.

Note

Releases are staged. Your Databricks account might not be updated with a new SQL warehouse version or Databricks SQL feature until a week or more after the initial release date.

Channels

Channels let you choose between the Current SQL warehouse compute version or the Preview version. Preview versions let you try out functionality before it becomes the Databricks SQL standard. Take advantage of preview versions to test your production queries and dashboards against upcoming changes.

Typically, a preview version is promoted to the current channel approximately two weeks after being released to the preview channel. Some features, such as security features, maintenance updates, and bug fixes, may be released directly to the current channel. From time to time, Databricks may promote a preview version to the current channel on a different schedule. Each new version will be announced in the following sections.

To learn how to switch an existing SQL warehouse to the preview channel, see Preview Channels. The features listed in the user interface updates sections are independent of the SQL Warehouse compute versions described in the Channels section of the release notes.

September 5, 2024

Changes in 2024.40

Databricks SQL version 2024.40 includes the following behavioral changes, new features, and improvements.

Behavioral changes

  • Change to the default schema binding mode for views

    Views now adapt to schema changes in the underlying query by using schema compensation with regular casting rules. This is a change from the previous default of BINDING mode, which raised errors when a safe cast could not be performed when referencing the view.

    See CREATE VIEW and cast function.

  • Disallow using the undocumented ! syntax instead of NOT outside boolean expressions

    With this release, the use of ! as a synonym for NOT outside of boolean expressions is no longer allowed. For example, statements such as the following: CREATE ... IF ! EXISTS, IS ! NULL, a ! NULL column or field property, ! IN and ! BETWEEN, must be replaced with: CREATE ... IF NOT EXISTS, IS NOT NULL, a NOT NULL column or field property, NOT IN and NOT BETWEEN.

    This change ensures consistency, aligns with the SQL standard, and makes your SQL more portable.

    The boolean prefix operator ! (for example, !is_mgr or !(true AND false)) is unaffected by this change.

  • Disallow undocumented column definition syntax in views

    Databricks supports CREATE VIEW with named columns and column comments. Previously, the specification of column types, NOT NULL constraints, or DEFAULT has been allowed. With this release, you can no longer use this syntax.

    This change ensures consistency, aligns with the SQL standard, and supports future enhancements.

  • Adding a CHECK constraint on an invalid column now returns the UNRESOLVED_COLUMN.WITH_SUGGESTION error class

    To provide more useful error messaging, in Databricks Runtime 15.3 and above, an ALTER TABLE ADD CONSTRAINT statement that includes a CHECK constraint referencing an invalid column name returns the UNRESOLVED_COLUMN.WITH_SUGGESTION error class. Previously, an INTERNAL_ERROR was returned.

New features and improvements

  • Enable UniForm Iceberg using ALTER TABLE

    You can now enable UniForm Iceberg on existing tables without rewriting data files. See Enable by altering an existing table.

  • UTF-8 validation functions

    This release introduces the following functions for validating UTF-8 strings:

    • is_valid_utf8 verified whether a string is a valid UTF-8 string.

    • make_valid_utf8 converts a potentially invalid UTF-8 string to a valid UTF-8 string using substitution characters

    • validate_utf8 raises an error if the input is not a valid UTF-8 string.

    • try_validate_utf8 returns NULL if the input is not a valid UTF-8 string.

  • to_avro and from_avro functions

    The to_avro and from_avro functions allow conversion of SQL types to Avro binary data and back.

  • try_url_decode function

    This release introduces the try_url_decode function, which decodes a URL-encoded string. If the string is not in the correct format, the function returns NULL instead of raising an error.

  • Optionally allow the optimizer to rely on unenforced foreign key constraints

    To improve query performance, you can now specify the RELY keyword on FOREIGN KEY constraints when you CREATE or ALTER a table.

  • Support for dropping the check constraints table feature

    Selective overwrites using replaceWhere now run jobs that delete data and insert new data in parallel, improving query performance and cluster utilization.

  • Parallelized job runs for selective overwrites

    Selective overwrites using replaceWhere now run jobs that delete data and insert new data in parallel, improving query performance and cluster utilization.

  • Improved performance for change data feed with selective overwrites

    Selective overwrites using replaceWhere on tables with change data feed no longer write separate change data files for inserted data. These operations use a hidden _change_type column present in the underlying Parquet data files to record changes without write amplification.

  • Improved query latency for the COPY INTO command

    This release includes a change that improves the query latency for the COPY INTO command. This improvement is implemented by making the loading of state by the RocksDB state store asynchronous. With this change, you should see an improvement in start times for queries with large states, such as queries with a large number of already ingested files.

User interface updates

The features listed in this section are independent of the SQL Warehouse compute versions described above.

Visualizations

  • Tooltip totals now appear only for stacked charts.

August 22, 2024

  • APIs for managing queries, alerts, data sources, and permissions have changed. The legacy version will continue to be supported for six months. This transition period is intended to give you sufficient time to migrate your applications and integrations to the new version before the older version is phased out. See Update to the latest Databricks SQL API version

July 18, 2024

User interface updates

Catalog explorer:

  • A new catalog configuration wizard is now available for setting up workspace bindings, catalog privileges, and metadata when creating a catalog.

SQL Warehouse monitoring:

  • CAN MONITOR permission is now generally available. It allows privileged users to monitor SQL warehouses, including the associated query history and query profiles. See SQL warehouse ACLs.

July 11, 2024

Databricks SQL Version 2024.35 Available

Rollout Schedule: Preview rollout for 2024.35: Between July 9th and July 15th

Changes in 2024.35

Disable column mapping with drop feature

You can now use DROP FEATURE to disable column mapping on Delta tables and downgrade the table protocol. See Disable column mapping.

Variant type syntax and functions in Public Preview

Built-in Apache Spark support for working with semi-structured data as VARIANT type is now available in Spark DataFrames and SQL. See Query variant data.

Variant type support for Delta Lake in Public Preview

You can now use VARIANT to store semi-structured data in tables backed by Delta Lake. See Variant support in Delta Lake.

Support for different modes of schema evolution in views

CREATE VIEW and ALTER VIEW now allow you to set a schema binding mode, enhancing how views handle schema changes in underlying objects. This feature enables views to either tolerate or adapt to schema changes in the underlying objects. It addresses changes in the query schema resulting from modifications to object definitions.

Performance improvement for some window functions

This release includes a change that improves the performance of some Spark window functions, specifically functions that do not include an ORDER BY clause or a window_frame parameter. In these cases, the system can rewrite the query to run it using an aggregate function. This change allows the query to run faster by using partial aggregation and avoiding the overhead of running window functions. The Spark configuration parameter spark.databricks.optimizer.replaceWindowsWithAggregates.enabled controls this optimization and is set to true by default. To turn this optimization off, set spark.databricks.optimizer.replaceWindowsWithAggregates.enabled to false.

Support for the try_mod function added

This release adds support for the PySpark try_mod() function. This function supports the ANSI SQL-compatible calculation of the integer remainder by dividing two numeric values. If the divisor argument is 0, the try_mod() function returns null instead of throwing an exception. You can use the try_mod() function instead of mod or %, which throws an exception if the divisor argument is 0 and ANSI SQL is enabled.

User interface updates

SQL Editor:

The inline assistant is now available in the SQL editor. Click the assistant icon in the editor box to toggle the input. Type a question or comment in English, then press Enter (not Shift+Enter, which runs a query) to generate a response with a different view directly in the editor.

Platform:

An API for notification destinations is now available. You can now programmatically manage webhook and email destinations for your alerts and job run notifications. See Notification Destinations.

July 4, 2024

Databricks SQL Version 2024.30 Available

Rollout schedule: Preview rollout for 2024.30: Between July 9th and July 15th

Changes in 2024.30

Lakehouse Federation is generally available (GA)

Lakehouse Federation connectors across the following database types are now generally available (GA):

  • MySQL

  • PostgreSQL

  • Amazon Redshift

  • Snowflake

  • Microsoft SQL Server

  • Azure Synapse (SQL Data Warehouse)

  • Databricks

This release also introduces the following improvements:

  • Support for additional pushdowns (string, math, miscellaneous functions).

  • Improved pushdown success rate across different query shapes.

  • Additional pushdown debugging capabilities:

    • The EXPLAIN FORMATTED output displays the pushed-down query text.

    • The query profile UI displays the pushed-down query text, federated node identifiers, and JDBC query execution times (in verbose mode). See View system-generated federated queries.

DESCRIBE HISTORY now shows clustering columns for tables that use liquid clustering

When you run a DESCRIBE HISTORY query, the operationParameters column shows a clusterBy field by default for CREATE OR REPLACE and OPTIMIZE operations. For a Delta table that uses liquid clustering, the clusterBy field is populated with the table’s clustering columns. If the table does not use liquid clustering, the field is empty.

Support for primary and foreign keys is generally available

Support for primary and foreign keys in Databricks Runtime is generally available. The GA release includes the following changes to the privileges required to use primary and foreign keys:

  • To define a foreign key, you must have the SELECT privilege on the table with the primary key that the foreign key refers to. You do not need to own the table with the primary key, which was previously required.

  • Dropping a primary key using the CASCADE clause does not require privileges on the tables that define foreign keys that reference the primary key. Previously, you needed to own the referencing tables.

  • Dropping a table that includes constraints now requires the same privileges as dropping tables that do not include constraints.

To learn how to use primary and foreign keys with tables or views, see CONSTRAINT clause, ADD CONSTRAINT clause, and DROP CONSTRAINT clause.

Liquid clustering is GA

Support for liquid clustering is now generally available using Databricks Runtime 15.2 and above. See Use liquid clustering for Delta tables.

Type widening is in Public Preview

You can now enable type widening on tables backed by Delta Lake. Tables with type widening enabled allow changing the type of columns to a wider data type without rewriting underlying data files. See Type widening.

Schema evolution clause added to SQL merge syntax

You can now add the WITH SCHEMA EVOLUTION clause to a SQL merge statement to enable schema evolution for the operation. See Schema evolution syntax for merge.

Vacuum inventory support

You can now specify an inventory of files to consider when running the VACUUM command on a Delta table. See the OSS Delta docs.

Support for Zstandard compression functions

You can now use the zst_compress, zstd_decompress, and try_zstd_decompress functions to compress and decompress BINARY data.

Query plans in the SQL UI now correctly display PhotonWriteStage

When displayed in the SQL UI, write commands in query plans incorrectly showed PhotonWriteStage as an operator. With this release, the UI is updated to show PhotonWriteStage as a stage. This is a UI change only and does not affect how queries are run.

Serverless SQL warehouses are now generally available.

Serverless SQL warehouses are now generally available in supported regions. They provide instant compute, minimal management, and cost optimization for SQL queries. Create serverless SQL warehouses or convert pro or classic SQL warehouses to serverless.

July 28, 2022

  • Alerts

    • Custom alert email templates have been updated to disallow certain HTML tags that may pose a security risk. Disallowed HTML tags and attributes are automatically sanitized. For example, <button> is a disallowed HTML tag, so instead of rendering a button, the text “button” displays. See Alerts for the list of allowed HTML tags and attributes.

    • Users can now subscribe other users to alerts without needing to create a notification destination, which requires admin permissions.

  • Downloads: Users can now download up to approximately 1GB of results data from Databricks SQL in CSV and TSV format, up from 64,000 rows previously.

  • Visualizations

    • You can now edit visualizations directly on the dashboard. In edit mode, click on the kebab menu and select Edit visualization to begin editing the visualization.

    • When downloading results associated with a visualization leveraging aggregations, the downloaded results are also aggregated. The option to download is moving from bottom kebab to the kebab associated with the tab. The downloaded results are from the most recent execution of the query that created the visualization.

  • SQL editor: Results tables now display a message when data displayed by the in-browser table has been limited to 64,000 rows. TSV and CSV download will still be up to approximately 1GB of data.

  • Query filters:

    • Query filters have been updated to work dynamically on either client- or server-side to optimize performance. Previous query filters (now legacy) operated client-side only. Users can still use legacy filters with the :: syntax, if desired.

    • The updated filters are simpler: Users click a +Add Filter button and select a column from a dropdown. Previously, users had to modify the query text directly.

    • Relevant values are highlighted to make it easier to see which selections within a filter will return results given other filter selections.

  • Query history: Query details in Query History now show the Query Source, which is the origin of the executed query.

July 21, 2022

    • In context help: on hover (for example, full table name, detailed Function panel) and inline execution error messages (for example, highlight row with error post execution)

    • Intelligent ranking of suggestions (for example, parameter autocompletion, ranking formula, less noisy matching)

July 14, 2022

  • You can now upload TSV files using the Create Table UI in addition to CSV files.

  • Databricks SQL now provides the option to notify users by email whenever a dashboard, query, or alert is shared with them.

  • Visualization tables now optionally include row numbers displayed next to results.

  • When you select a geographic region for the Chloropleth visualization, you now get inline hints for accepted values.

June 23, 2022

  • SQL endpoint name change: Databricks changed the name from SQL endpoint to SQL warehouse because it is more than just an API entry point for running SQL commands. A SQL warehouse is a computation resource for all your data warehousing needs, an integral part of the Databricks platform. Compute resources are infrastructure resources that provide processing capabilities in the cloud.

  • For Choropleth visualizations, the Key column and Target field selections in the visualization editor have been renamed to Geographic Column and Geographic Type. This renaming for understandability does not introduce any behavior changes to new or existing Choropleths.

  • The limit 1000 query option has moved from a checkbox in the SQL query editor to a checkbox in the run button.

  • Cached queries in Query History table are now marked with a Cache tag.

  • Manually refreshing a dashboard uses the dashboard’s warehouse (if available) instead of each individual query’s warehouse.

  • Refreshing an alert always uses the alert’s warehouse, regardless of the Run as Viewer/Owner setting.

June 9, 2022

  • When you hover in the endpoint selector, the full endpoint name is displayed as a tooltip.

  • When you filter in the SQL editor schema browser, the search term is now highlighted in the search results.

  • You can now add data labels to combination charts.

  • The list of visualization aggregations operations now includes variance and standard deviation.

May 26, 2022

Authoring improvements:

  • You can now bypass aggregations when you author visualizations. This is particularly useful when your query already includes an aggregation. For example, if your query is SELECT AVG(price_per_sqft), isStudio, location GROUP BY location, isStudio, the chart editor previously required explicitly specifying another layer of aggregation.

  • When you author dashboards, you now have the ability to:

    • Duplicate textbox widgets

    • Expand the size of the edit textbox panel

  • The default aggregation for the error column when you author visualizations is standard deviation.

Fixes:

  • Edit actions for visualizations are only available when the dashboard is in edit mode. Edit actions are no longer available as a view mode action.

  • When you create a new query, it opens in a tab to the immediate right of the tab in focus rather than at the end of the list.

  • The open query modal shows which query is already open and provides the option to switch focus to that query tab.

  • The Sankey & Sunburst charts no longer treat 0 as null.

May 19, 2022

  • Fixed issue: When you have the focus of the SQL editor open on a specific visualization tab and share the link to another user, the user will have the same focus in the SQL editor when they click the shared link.

  • Improvements:

    • Microsoft Teams is now a supported notification destination.

    • The Date Range, Date and Time Range, and Date and Time Range (with seconds) parameters now support the option to designate the starting day of the week, with Sunday as the default.

  • Visualizations now support time binning directly in the UI. You can now easily switch between yearly, monthly, daily, or hourly bins of your data by changing a dropdown value rather than adding and modifying a date_trunc() function in the query text itself.

  • Dashboards now have color consistency by default. If you have the same series across multiple charts, the series is always colored the same across all charts – without requiring any manual configuration.

  • When sharing a dashboard with a user or group, we now also provide the ability to share all upstream queries used by visualizations and parameters.

    • When you do not have permission to share one or more of the upstream queries, you will receive a warning message that not all queries could be shared.

    • The permissions granted when sharing a dashboard do not override, negate, or expand upon existing permissions on the upstream queries. For example, if a user or group has CAN RUN as Owner permissions on the shared dashboard but only has Run as Viewer permissions on an upstream query, the effective permissions on that upstream query will be Run as Viewer.

  • Databricks SQL is now available in Public Preview on Google Cloud Platform.

Known issues

  • Reads from data sources other than Delta Lake in multi-cluster load balanced SQL endpoints can be inconsistent.

  • Delta tables accessed in Databricks SQL upload their schema and table properties to the configured metastore. If you are using an external metastore, you will be able to see Delta Lake information in the metastore. Delta Lake tries to keep this information as up-to-date as possible on a best-effort basis. You can also use the DESCRIBE <table> command to ensure that the information is updated in your metastore.

  • Databricks SQL does not support zone offsets like ‘GMT+8’ as session time zones. The workaround is to use a region based time zone https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) like ‘Etc/GMT+8’ instead. See SET TIME ZONE for more information about setting time zones.

Frequently asked questions (FAQ)

How are Databricks SQL workloads charged?

Databricks SQL workloads are charged according to the Premium Jobs Compute SKU.

Where do SQL endpoints run?

Like Databricks clusters, SQL endpoints are created and managed in your Google Cloud account. SQL endpoints manage SQL-optimized clusters automatically in your account and scale to match end-user demand.

Can I use SQL endpoints from Data Science & Engineering workspace SQL notebooks?

No. You can use SQL endpoints from Databricks SQL queries, BI tools, and other JDBC and ODBC clients.

I have been granted access to data using a cloud provider credential. Why can’t I access this data in Databricks SQL?

In Databricks SQL, all access to data is subject to data access control, and an administrator or data owner must first grant you the appropriate privileges.
