public OpenLineageClient(String serverName,
 String serverPlatformURLRoot)
                  throws InvalidParameterException

Create a new OpenLineage client.

Parameters:

serverName - name of the server to connect to

serverPlatformURLRoot - the network address of the server running the OMAS REST services

Throws:

InvalidParameterException - if parameter validation fails

Method Details

lineage

public LineageVerticesAndEdges lineage(String userId,
 Scope scope,
 String guid,
 boolean includeProcesses)
                                throws InvalidParameterException,
PropertyServerException,
OpenLineageException

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, SOURCE_AND_DESTINATION, VERTICAL, END_TO_END.

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

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

PropertyServerException - problem contacting the metadata server

OpenLineageException - open lineage exception
