Export dataflows involving File System into Alation

At my organization, the Informatica Power Center is used to process critical data elements(CDE) from different Applications relying on several technologies like Oracle, MSSQL, DB2 LUW, PWX,NRDB2,Salesforce, FileSystem,PWX Db2 ZOS, Netezza.

Data Governance Stewards are using Manta Platform to scan and analyze these applications in Bank. Further to identify the source of origin holding these CDE’s and do impact analysis of the change one of these or all CDE’s if any.Once the Data lineage is validated in Manta .Next step is to export the Data Lineage from Manta to Alation for the regulators and auditors to review .

We analyzed few of the applications folders and majority of the DataFlows are using source or target as File System.

For an example one of the applications is using source as Oracle and Target as File Sytem in the Dataflow , and there is no way to scan the underlying File System in Manta. As a result, the dataflow generated for export is incorrect in Manta and cannot be exported to Alation. There is no mechanism to map Manta File System to Alation File System (Native or Virtual or Both ).

Business impact: Any lineage that involves files system cannot be exported to Alation.

Expected Outcome:

Manta should provide a way to export DataFlows involving FileSystem into Alation. These could be done either by Mapping Alation File System( Native or Virtual or Both) to Manta files or even as Alation External objects.

    Hi Dev,

    the functionality was designed with local filesystems brought in through Manta by other scanners as well. For the export to work, you need to provide a mapping for the filesystem. In your PowerCenter example, you already have an existing mapping for PowerCenter itself, to leverage the export of filesystems you need to add a mapping for the filesystem under PowerCenter too - see this section of documentation https://www.ibm.com/docs/en/manta-data-lineage?topic=mfea-manta-flow-alation-automatic-data-lineage-alation-resource-mapping#filesystem-resource-mapping-config . Please locate the filesystem node under PowerCenter in Manta Repository page, copy it's path and use it as "Filesystem path" in this mapping.

    Happy to assist with this on a call if needed.

    Best Regards

    @jakub, we evaluated the solution present in 42.12 and it seems insufficient. Alation only supports filesystems of type: s3, hdfs, azure. However when Manta scans informatica powercenter, the lineage shows up local filesystems as well, such as NFS.

    The current system doesnt seem to support exporting local or NFS filesystems to Alation via EXT objects.

    This seems to be under review for many days now. Do you have any progress to share here?
