DESCRIPTION
    Allows users to auto discover BigQuery External and BigLake tables from
    underlying Cloud Storage buckets.

EXAMPLES
    To update description of a data discovery scan data-discovery-datascan in
    project test-project located in us-central1, run:

        $ gcloud dataplex datascans update data-discovery \
            data-discovery-datascan --project=test-project \
            --location=us-central1 --description="Description is updated."

POSITIONAL ARGUMENTS
     Datascan resource - Arguments and flags that define the Dataplex datascan
     you want to update a data discovery scan for. The arguments in this group
     can be used to specify the attributes of this resource. (NOTE) Some
     attributes are not given arguments in this group but can be set in other
     ways.

     To set the project attribute:
      ◆ provide the argument datascan on the command line with a fully
        specified name;
      ◆ provide the argument --project on the command line;
      ◆ set the property core/project.

     This must be specified.

       DATASCAN
          ID of the datascan or fully qualified identifier for the datascan.

          To set the dataScans attribute:
          ▸ provide the argument datascan on the command line.

          This positional argument must be specified if any of the other
          arguments in this group are specified.

       --location=LOCATION
          The location of the Dataplex resource.

          To set the location attribute:
          ▸ provide the argument datascan on the command line with a fully
            specified name;
          ▸ provide the argument --location on the command line;
          ▸ set the property dataplex/location.

FLAGS

     --display-name=DISPLAY_NAME
        Display name of the data discovery scan

     --labels=[KEY=VALUE,...]
        List of label KEY=VALUE pairs to add.

        Keys must start with a lowercase character and contain only hyphens
        (-), underscores (_), lowercase characters, and numbers. Values must

          complete.

       --validate-only
          Validate the update action, but don't actually perform it.

     Data spec for the data discovery scan.

       BigQuery publishing config arguments for the data discovery scan.

         --bigquery-publishing-connection=BIGQUERY_PUBLISHING_CONNECTION
            BigQuery connection to use for auto discovering cloud resource
            bucket to BigLake tables. Connection is required for
            BIGLAKE`BigQuery publishing table type.

         --bigquery-publishing-dataset-location=BIGQUERY_PUBLISHING_DATASET_LOCATION
            The location of the BigQuery dataset to publish BigLake external or
            non-BigLake external tables to. If not specified, the dataset
            location will be set to the location of the data source resource.
            Refer to
            https://cloud.google.com/bigquery/docs/locations#supportedLocations
            for supported locations.

         --bigquery-publishing-dataset-project=BIGQUERY_PUBLISHING_DATASET_PROJECT
            The project of the BigQuery dataset to publish BigLake external or
            non-BigLake external tables to. If not specified, the cloud
            resource bucket project will be used to create the dataset. The
            format is "projects/{project_id_or_number}.

         --bigquery-publishing-table-type=BIGQUERY_PUBLISHING_TABLE_TYPE
            BigQuery table type to discover the cloud resource bucket. Can be
            either EXTERNAL or BIGLAKE. If not specified, the table type will
            be set to EXTERNAL.

       Storage config arguments for the data discovery scan.

         --storage-exclude-patterns=[PATTERN,...]
            List of patterns that identify the data to exclude during
            discovery. These patterns are interpreted as glob patterns used to
            match object names in the Cloud Storage bucket. Exclude patterns
            will be applied before include patterns.

         --storage-include-patterns=[PATTERN,...]
            List of patterns that identify the data to include during discovery
            when only a subset of the data should be considered. These patterns
            are interpreted as glob patterns used to match object names in the
            Cloud Storage bucket.

         CSV options arguments for the data discovery scan.

           --csv-delimiter=CSV_DELIMITER
              Delimiter used to separate values in the CSV file. If not
              specified, the delimiter will be set to comma (",").

           --csv-disable-type-inference=CSV_DISABLE_TYPE_INFERENCE
              Whether to disable the inference of data types for CSV data. If
              true, all columns are registered as strings.

           --csv-encoding=CSV_ENCODING
              Character encoding of the CSV file. If not specified, the
              encoding will be set to UTF-8.

           --csv-header-row-count=CSV_HEADER_ROW_COUNT
              The number of rows to interpret as header rows that should be

           --csv-quote-character=CSV_QUOTE_CHARACTER
              The character used to quote column values. Accepts " (double
              quotation mark) or ' (single quotation mark). If unspecified,
              defaults to " (double quotation mark).

         JSON options arguments for the data discovery scan.

           --json-disable-type-inference=JSON_DISABLE_TYPE_INFERENCE
              Whether to disable the inference of data types for JSON data. If
              true, all columns are registered as strings.

           --json-encoding=JSON_ENCODING
              Character encoding of the JSON file. If not specified, the
              encoding will be set to UTF-8.

     Data discovery scan execution settings.

       Data discovery scan scheduling and trigger settings

       At most one of these can be specified:

         --on-demand=ON_DEMAND
            If set, the scan runs one-time shortly after data discovery scan
            updation.

         --schedule=SCHEDULE
            Cron schedule (https://en.wikipedia.org/wiki/Cron) for running
            scans periodically. To explicitly set a timezone to the cron tab,
            apply a prefix in the cron tab: "CRON_TZ=${IANA_TIME_ZONE}" or
            "TZ=${IANA_TIME_ZONE}". The ${IANA_TIME_ZONE} may only be a valid
            string from IANA time zone database. For example,
            CRON_TZ=America/New_York 1 * * * * or TZ=America/New_York 1 * * *
            *. This field is required for RECURRING scans.
