• Insights dashboard: Revamps the Insights dashboard to provide data visualization of Org-level Pipeline-execution statistics for a specific date range.
  

  
  
  
  

• Task monitoring: Adds a new tab for Tasks under Dashboard that does data visualization of triggered and scheduled tasks for a selected time range. The new tab displays the number of failed and completed executions for each task type along with their details.
  

  
  
  
  

• Snap auto-configuration: Enhances the suggestion capabilities of Iris to include Snap auto-configuration in Snaps with suggestible properties. Iris Expression recommends the configuration of these properties based on similar Snap settings from Pipelines that you can access. 
  

  
  
  
  

• Sticky Notes in SnapLogic Designer: Introduces the ability to add notes to a Pipeline in SnapLogic Designer. This enables you to collaborate with multiple Pipeline developers or add important notes for complex Pipelines. The notes are included in the Pipeline metadata and are immediately visible to other users accessing the Pipeline.
  

  
  
  

• Target recommendation: Enhances the Iris Expression recommendation capabilities to include Target path suggestions in Mapper Snap. Iris recommends Target paths based on exact matches between Expression and Target paths from other Pipelines in your Org.

• A Triggered Task on a Groundplex with an underlying Pipeline that contains child Pipelines might stall as the Data Validator Snap is executing in the parent Pipeline.

• An Ultra Pipeline sometimes processes the same message twice even though the message was processed successfully during the first attempt. 

• Starting in the 4.21 Release (May 2020), the escaping required in the replacement text of the ReplaceAll function is identical to that of the Replace function. Prior to this release, you had to use additional escaping in the replacement text with ReplaceAll to get the desired output.

• Starting in the 4.21 Release (May 2020), the Date.parse() function returns the response text Not a Number when you enter a non-number or infinity. Prior to this release, doing either resulted in an error, even though the formatting of the string was correct.

  • Enhances the Deduplicate Snap to add a new field, Group ID, which includes the Group ID for each record in the output. Also, enhances the Comparator field in the Snap by adding one more option, Exact, which identifies and classifies a match as either an exact match or not a match at all.

For example, if Snaps downstream from the Mapper Snap have custom fields that contain multiple keys, then these keys automatically display in the Mapper Snap's Target Schema dropdown list when you toggle-off Expression Builder and select the field in the Mapping Table.

• In some Snaps, if you leave any expression-enabled mandatory fields empty, a null pointer exception error message might display instead of the usual error message on validation.

• Cassandra: 

  • The Cassandra Snap Pack does not support the following data types introduced in Apache Cassandra V3.x:

    • DateRange

    • Duration

    • Geo-spatial data types such as Point, Polygon and LineString

  • Snaps in this Snap Pack display an exception when you query a map column that has a timestamp as the key.

• MySQL: When MySQL Execute Snaps (MySQL - Execute and MySQL - Multi Execute) are followed by MySQL Snaps, such as MySQL - Insert, MySQL - Merge, they display the following error when executed: 
  Table definition has changed, please retry transaction.

  This happens due to a known issue in the MySql Database. For more information, see MySQL Bug #65378.

• Parquet Writer (Behavior Change): In the 4.20 Snap version (snapsmrc535 and hadoop8776) when a value for a field defined as repeated (for example, devops in the below example) is not present in the input document, the Parquet Writer Snap displays "The required field 'devops' is missing from a document" error. However, in the 4.21 release, the Parquet Writer Snap outputs a null value when there is no input for the repeated fields. If this behavior change impacts your existing Pipelines having the Parquet Writer Snap, then you might want to consider potentially redesigning your impacted Pipelines.

  repeated group devops { required binary lan (UTF8); optional binary lan2 (UTF8); }

During the May2020, 4.21 release cycle, we did multiple enhancements to the third-party dependencies used by the SnapLogic platform and the Snaps. Hence, we strongly recommend updating and redeploying all your custom Snap Packs to ensure compatibility with this release. For details, see Updating Custom Snap Packs in the SnapLogic Developer Documentation.

 The following 4.20 Snap Dot Release updates are now a part of the current 4.21 GA release.
