      • setSourceUris

        public ExternalTableDefinition.Builder setSourceUris​(List<String> sourceUris)
        Sets the fully-qualified URIs that point to your data in Google Cloud Storage (e.g. gs://bucket/path). Each URI can contain one '*' wildcard character that must come after the bucket's name. Size limits related to load jobs apply to external data sources, plus an additional limit of 10 GB maximum size across all URIs.

        For Google Cloud Bigtable URIs: Exactly one URI can be specified and it has be a fully specified and valid HTTPS URL for a Google Cloud Bigtable table.

        For Google Cloud Datastore backup URIs: Exactly one URI can be specified. Also, the '*' wildcard character is not allowed.

      • setDecimalTargetTypes

        public abstract ExternalTableDefinition.Builder setDecimalTargetTypes​(List<String> decimalTargetTypes)
        Defines the list of possible SQL data types to which the source decimal values are converted. This list and the precision and the scale parameters of the decimal field determine the target type. In the order of NUMERIC, BIGNUMERIC, and STRING, a type is picked if it is in the specified list and if it supports the precision and the scale. STRING supports all precision and scale values.
        Parameters:
        decimalTargetTypes - decimalTargetType or null for none

      • setMaxBadRecords

        public abstract ExternalTableDefinition.Builder setMaxBadRecords​(Integer maxBadRecords)
        Sets the maximum number of bad records that BigQuery can ignore when reading data. If the number of bad records exceeds this value, an invalid error is returned in the job result. The default value is 0, which requires that all records are valid.

      • setIgnoreUnknownValues

        public abstract ExternalTableDefinition.Builder setIgnoreUnknownValues​(Boolean ignoreUnknownValues)
        Sets whether BigQuery should allow extra values that are not represented in the table schema. If true, the extra values are ignored. If false, records with extra columns are treated as bad records, and if there are too many bad records, an invalid error is returned in the job result. The default value is false. The value set with setFormatOptions(FormatOptions) property determines what BigQuery treats as an extra value.

      • setAutodetect

        public abstract ExternalTableDefinition.Builder setAutodetect​(Boolean autodetect)
        [Experimental] Sets detection of schema and format options automatically. Any option specified explicitly will be honored.

      • setReferenceFileSchemaUri

        public abstract ExternalTableDefinition.Builder setReferenceFileSchemaUri​(String referenceFileSchemaUri)
        When creating an external table, the user can provide a reference file with the table schema. This is enabled for the following formats: AVRO, PARQUET, ORC.
        Parameters:
        referenceFileSchemaUri - or null for none
