Returns the graph that the user will initially see when querying lineage. In the future, this method will be extended to condense large paths to prevent cluttering of the users screen. The user will be able to extended the condensed path by querying a different method.

Specified by:

lineage in interface OpenLineageInterface

Parameters:

userId - calling user.

scope - ULTIMATE_SOURCE, ULTIMATE_DESTINATION, GLOSSARY.

view - TABLE_VIEW, COLUMN_VIEW.

guid - The guid of the node of which the lineage is queried of.

displayNameMustContain - Used to filter out nodes which displayname does not contain this value.

includeProcesses - Will filter out all processes and subprocesses from the response if false.

Returns:

A subgraph containing all relevant paths, in graphSON format.

Throws:

InvalidParameterException - one of the parameters is null or invalid
