Should be A. Curated zone need Parquet, Avro, ORC format not CSV or JSON. Check the ref - https://cloud.google.com/dataplex/docs/add-zone#curated-zones

- Auto-Discovery Feature: Dataplex has an auto-discovery feature that, when enabled, automatically discovers and catalogs data assets within a zone. - Appropriate for Both Raw and Curated Zones: This feature is applicable to both raw and curated zones, and it should be tailored to the specific data governance and cataloging needs of the organization.

Option A https://cloud.google.com/dataplex/docs/add-zone#raw-zones Raw zones are the only zones that support CSV & JSON

Its B guys, i encounter this in my job, and I had to do B to make it work

GCP001 agree with him

The answer can be found reading a common config of Dataplex in this URL: https://medium.com/google-cloud/google-cloud-dataplex-part-1-lakes-zones-assets-and-discovery-5f288486cb2f

Dataplex does not allow users to create CSV files within a “curated zone”

According to this URL: https://cloud.google.com/dataplex/docs/discover-data, the auto-discovery can support CSV and Json in both Raw-Zone and Curated-Zone. I also open a console the verify it, both Raw and Curated zone can set up csv&json auto-discovery.

Discovery raises the following administrator actions whenever data-related issues are detected during scans : Inconsistent data format in a table. For example, files of different formats exist with the same table prefix. Inconsistent data format in a table. For example, files of different formats exist with the same table prefix.

I'd go for Option B, auto-discovery is enabled by default for any zone, including curated ones, so if a file is not automatically discovered it's due to the disabled auto-discovery

I will go with A, check the ref. Curated zones only store Parquet, Avro, and ORC in CS, and well-defined schema and Hive-style partitions in the BigQuery: https://cloud.google.com/dataplex/docs/add-zone#curated-zones

A. Move the JSON and CSV files to the raw zone.
