v5.5.0

Release Notes for Data Hub 5.5.0

Release Summary

Data Hub 5.5.0 includes the following new features and changes:
Important: Upgrading to this release would trigger a reindexing of the STAGING and FINAL databases. Learn more about how reindexing works and its impact on performance.
Notices

• QuickStart is now deprecated. Hub Central supports all the same functionality and should be used instead. As of 5.5, match and merge steps can only be configured and run in Hub Central.
• Custom hooks are now deprecated, and interceptors should be used instead.

General enhancements

• New option to run a step interceptor before the primary function is invoked (to do this, specify  "when" as "beforeMain")
• Support for testing Data Hub steps with marklogic-unit-test and JUnit 5 (see Testing Data Hub Applications)
• Ingest and run a Data Hub flow of steps in a single call via a new REST extension or MLCP. When you specify more than one step, the output of one step is the input to the next step. This is a more performant way to ingest and run multiple steps since it involves only one call to MarkLogic (see Run Multiple Steps on Ingest)
• Ability to facet on structured types in Hub Central's Explore feature
• When Data Hub writes documents via a step, documents are now written to the user's default collections
• You can now set 'quality' to documents created by a step to control the relevance score of documents in text searches

Mapping enhancements (see Mapping Enhancements)

• Support for mapping multiple entities from a single source document within the same step
• A new Attach Source Document field in mapping settings lets you specify whether the source document should be copied into the mapped entity instance. 
• A new URI field in every mapping configuration lets you define a URI template as a mapping expression. A new mapping function called hubURI generates a UUID and prefixes the name of the specified entity type. The function signature is hubURI(entityType).
• You can define custom parameters that are referenced from a mapping expression. 

Mastering enhancements

• Configure match and merge steps in HC for structured properties
• Test your configuration for matching
  • View total match scores and broken down match contributions for each property
  • View documents side-by-side to compare similarities and differences

Monitoring enhancements
