Method Detail

compression

@Deprecated
public String compression()

Deprecated.

Returns the compression type of the data source.

See Also:

Compression

getCompression

public String getCompression()

Returns the compression type of the data source.

See Also:

Compression

ignoreUnknownValues

public Boolean ignoreUnknownValues()

Returns 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 of formatOptions() determines what BigQuery treats as an extra value.

Ignore Unknown Values

maxBadRecords

@Deprecated
public Integer maxBadRecords()

Deprecated.

Returns 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.

getMaxBadRecords

public Integer getMaxBadRecords()

Returns 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.

sourceUris

@Deprecated
public List<String> sourceUris()

Deprecated.

Returns the fully-qualified URIs that point to your data in Google Cloud Storage. 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.

See Also:

Quota

getSourceUris

public List<String> getSourceUris()

Returns the fully-qualified URIs that point to your data in Google Cloud Storage. 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.

See Also:

Quota

formatOptions

@Deprecated
public <F extends FormatOptions> F formatOptions()

Deprecated.

Returns the source format, and possibly some parsing options, of the external data. Supported formats are CSV and NEWLINE_DELIMITED_JSON.

getFormatOptions

public <F extends FormatOptions> F getFormatOptions()

Returns the source format, and possibly some parsing options, of the external data. Supported formats are CSV and NEWLINE_DELIMITED_JSON.
