Weekly Release Notes Recap
Here’s a quick recap of the latest release notes updates from the past one week.
Databricks platform release notes
December 5 - 16, 2022
Databricks JDBC driver 2.6.32
Version 2.6.32 of the Databricks JDBC driver (download and Maven) is now available. This release updates the Jackson JSON parser libraries for enhanced security:
- jackson-annotations-2.13.4 (previously 2.13.2)
- jackson-core-2.13.4 (previously 2.13.2)
- jackson-databind-2.13.4.2 (previously 2.13.2.2)
This release also resolves the following issues:
- When using cloud fetch, the driver now cleans up certain resources properly.
- The driver previously included cloud fetch’s presigned URLs in its log file. These presigned URLs included sensitive tokens. These log entries now exclude these tokens.
- The driver logs a SQL statement whenever its execution hits an exception. Statements such as COPY INTO might contain secrets (for example WITH CREDENTIAL). Driver log entries now exclude such credentials.
For full details, see release-notes.txt included with the driver.
Databricks ODBC driver 2.6.29
Version 2.6.29 of the Databricks ODBC driver (download) is now available. This release adds support for Unity catalog’s primary and foreign keys, thereby enabling BI tools that use the ODBC driver to discover relationships between tables during data modeling.
This release also resolves the following issue:
- The driver previously included cloud fetch’s presigned URLs in its log file when EnableCurlDebugLogging is set. These presigned URLs included sensitive tokens. Driver log entries now exclude these tokens.
For full details, see release-notes.txt included with the driver.
Jobs are now available in global search
You can now search for jobs in the top bar of your Databricks workspace.
Capturing lineage data with Unity Catalog is now generally available
Databricks is pleased to announce the general availability of Unity Catalog support for capturing and viewing lineage data. See Capture and view data lineage with Unity Catalog.
Databricks SQL release notes
December 8, 2022
Web application user interface updates
- Databricks SQL alerts now support alerts for aggregations of query result columns such as SUM, COUNT, and AVG.
- The default visualization title is now ‘VisualizationName - QueryName’ when creating new widgets on dashboards.
Databricks Connect for Databricks Runtime 11.3 LTS
December 8, 2022
Databricks Connect 11.3.0b0
- Initial Databricks Connect client release to support Databricks Runtime 11.3 LTS.
- There is a known issue in the R integration (some Spark plans will fail to execute).
Delta Live Tables release notes
December 6, 2022
Release 2022.49
Changes
- You can now import files from a Databricks Repo as Python modules. You can import files from the current directory or a specified location using sys.path.append().
- Enhanced Autoscaling is now generally available. With this release, Enhanced Autoscaling is the default autoscaling mode for new pipelines created in the UI. Databricks recommends updating pipelines that use the existing cluster autoscaling to use Enhanced Autoscaling. For more information about Enhanced Autoscaling, see Databricks Enhanced Autoscaling. For more information about configuring Enhanced Autoscaling when you create or edit a pipeline, see Create, run, and manage Delta Live Tables pipelines.
- For pipelines run in continuous mode, the default retry limit is now 2 when retryable failures occur. Including the original attempt, all flows have three attempts (with exponential backoff) to run when non-fatal failures occur. Previously, the defaults were unbounded retries for batch flows, and five retries for streaming flows. See Delta Live Tables settings.
- The configuration parameter pipelines.maxFlowRetryAttempts now applies to the retry limit for all flows, including batch and streaming flows, and continuous or triggered pipelines. Previously, pipelines.maxFlowRetryAttempts applied to all retry limits in triggered mode but only batch flows in continuous mode; retries for streaming pipelines in continuous mode were controlled by pipelines.numStreamRetryAttempts. For existing pipelines, pipelines.numStreamRetryAttempts continues to be supported for streaming flows in continuous mode. If both pipelines.numStreamRetryAttempts and pipelines.maxFlowRetryAttempts are set, pipelines.numStreamRetryAttempts takes priority for streaming flows in continuous mode. Otherwise, the configured value for pipelines.maxFlowRetryAttempts is used. See Delta Live Tables settings.
Bug fixes
- This release fixes a bug causing display of incorrect DBU per hour calculations for Photon-enabled clusters.
- This release fixes a bug causing Delta Live Tables maintenance tasks to fail in Unity Catalog enabled workspaces.
- This release fixes a bug where stopping or restarting a continuous pipeline that ingests data with Auto Loader causes the pipeline to hang for several minutes.
