Overview : 

Fetch CM Handles by collection of xpaths using temp table in NCMP/RI-Module

• Create a plural version of "org.onap.cps.api.CpsDataService#getDataNode" with
  • Collection of xpaths
  • fetchDescendantsOption? TBD (Check if it can be easily added, we can hard code to include all the descendents or make it optional)
• It should use new algorithm / method in the persistence service (using a temp table)
• Extend fragment repository with the custom extension that makes use of java and (native) sql like "org.onap.cps.spi.repository.FragmentRepositoryCpsPathQueryImpl#findByAnchorAndCpsPath"
  • The extension would create a temp table from the list of xpaths.
  • Create a version of query below using all xpaths in the temp table instead of single xpath: org.onap.cps.spi.repository.FragmentRepository#findByAnchorIdAndParentXpath
• Use and refactor methods to return collection of data nodes (new) as well as a version for a single DataNode (existing).

A/C :

• Review only as it should use only one query with collection of xpaths

Open Questions :

1. Java / REST Interface ?  Java interface as it's internal use only

Out of Scope :

• No Demo
• No NCMP update (done in separate Jira)
