Welcome to Release 5.1 of Designer Cloud Enterprise Edition! This release includes a significant expansion in database support and connectivity with more running environment versions, such as Azure Databricks. High availability is now available on the Designer Cloud Powered by Trifacta platform node itself.
Within the Transformer page, you should see a number of enhancements, including improved toolbars and column menus. Samples can be named.
Regarding operationalization of the platform, datasets with parameters can now accept Alteryx patterns for parameter specification, which simplifies the process of creating complex matching patterns. Additionally, you can swap out a static imported dataset for a dataset with parameters, which enables development on a simpler dataset before expanding to a more complex set of sources. Variable overrides can now be applied to scheduled job executions, and you can specify multiple variable overrides in Flow View.
The underlying language has been improved with a number of transformations and functions, including a set of transformations designed around preparing data for machine processing. Details are below.
Tip: For a general overview of the product and its capabilities, see Product Overview.

Changes to System Behavior
Diagnostic Server removed from product
The Diagnostic Server and its application page have been removed from the product. This feature has been superseded by Tricheck, which is available to administrators through the application. For more information, see Admin Settings Page.

Case-sensitive variations in date range values are not matched when creating a dataset with parameters.
NOTE: Date range parameters are now case-insensitive.
Job execution on recipe with high limit in split transformation due to Java Null Pointer Error during profiling.
NOTE: Avoid creating datasets that are wider than 2500 columns. Performance can degrade significantly on very wide datasets.

Matching file path patterns in a large directory can be very slow, especially if using multiple patterns in a single dataset with parameters.
NOTE: To increase matching speed, avoid wildcards in top-level directories and be as specific as possible with your wildcards and patterns.
|TD-30854||When creating a new dataset from the Export Results window from a CSV dataset with Snappy compression, the resulting dataset is empty when loaded in the Transformer page.|
Some string comparison functions process leading spaces differently when executed on the Trifacta Photon or the Spark running environment.
|TD-30717||No validation is performed for Redshift or SQL DW connections or permissions prior to job execution. Jobs are queued and then fail.|
|TD-27860||When the platform is restarted or an HA failover state is reached, any running jobs are stuck forever In Progress.|
New Known Issues
After installing on Ubuntu 16.04 (Xenial), platform may fail to start with "ImportError: No module named pkg_resources" error.
Workaround: Verify installation of
|TD-35644||Compilation/Execution||Extractpatterns for "HTTP Query strings" option doesn't work.|
When executing Spark 2.3.0 jobs on S3-based datasets, jobs may fail due to a known incompatibility between HTTPClient:4.5.x and aws-java-jdk:1.10.xx. For details, see https://github.com/apache/incubator-druid/issues/4456.
Workaround: Use Spark 2.1.0 instead. In Admin Settings page, configure the
For additional details on Spark versions, see Configure for Spark.
Clicking Cancel Job button generates a 405 status code error. Click Yes button fails to close the dialog.
Workaround: After you have clicked the Yes button once, you can click the No button. The job is removed from the page.
Spark jobs fail on LCM function that uses negative numbers as inputs.
Workaround: If you wrap the negative number input in the ABS function, the LCM function may be computed. You may have to manually check if a negative value for the LCM output is applicable.
Differences in how WEEKNUM function is calculated in Trifacta Photon and Spark running environments, due to the underlying frameworks on which the environments are created.
For more information, see WEEKNUM Function.
The Spark running environment does not support use of multi-character delimiters for CSV outputs. For more information on this issue, see https://issues.apache.org/jira/browse/SPARK-24540.
Workaround: You can switch your job to a different running environment or use single-character delimiters.
|TD-34840||Transformer Page||Platform fails to provide suggestions for transformations when selecting keys from an object with many of them.|
|TD-34119||Compilation/Execution||WASB job fails when publishing two successive appends.|
Creating dataset from Parquet-only output results in "Dataset creation failed" error.
NOTE: If you generate results in Parquet format only, you cannot create a dataset from it, even if the Create button is present.
You cannot publish ad-hoc results for a job when another publishing job is in progress for the same job.
Workaround: Please wait until the previous job has been published before retrying to publish the failing job.
For multi-file imports lacking a newline in the final record of a file, this final record may be merged with the first one in the next file and then dropped in the Trifacta Photon running environment.
Workaround: Verify that you have inserted a new line at the end of every file-based source.
