java.lang.Object

org.apache.nifi.atlas.provenance.AbstractNiFiProvenanceEventAnalyzer

org.apache.nifi.atlas.provenance.analyzer.AzureADLSDirectory

All Implemented Interfaces:

NiFiProvenanceEventAnalyzer

public class AzureADLSDirectory
extends AbstractNiFiProvenanceEventAnalyzer

Analyze a transit URI as an Azure ADLS Gen2 directory (skipping the file name).

Atlas entity hierarchy: adls_gen2_directory -> adls_gen2_directory -> ... -> adls_gen2_container -> adls_gen2_account

adls_gen2_directory

• qualifiedName=abfs://filesystem@account/path@namespace (example: abfs://myfilesystem@myaccount/mydir1/mydir2/@ns1)
• name=directory (example: mydir2)

adls_gen2_container

• qualifiedName=abfs://filesystem@account@namespace (example: abfs://myfilesystem@myaccount@ns1)
• name=filesystem (example: myfilesystem)

adls_gen2_account

• qualifiedName=abfs://account@namespace (example: abfs://myaccount@ns1)
• name=account (example: myaccount)
