Method Details

getTable

public @Nullable Table getTable(TableReference tableRef)
                         throws IOException,
InterruptedException

Gets the specified Table resource by table ID.

Returns null if the table is not found.

Tries executing the RPC for at most MAX_RPC_RETRIES times until it succeeds.

Specified by:

getTable in interface BigQueryServices.DatasetService

Throws:

IOException - if it exceeds MAX_RPC_RETRIES attempts.

InterruptedException

getTable

public @Nullable Table getTable(TableReference tableRef,
 List<String> selectedFields)
                         throws IOException,
InterruptedException

Specified by:

getTable in interface BigQueryServices.DatasetService

Throws:

IOException

InterruptedException

getTable

public @Nullable Table getTable(TableReference tableRef,
 List<String> selectedFields,
 BigQueryServices.DatasetService.TableMetadataView view)
                         throws IOException,
InterruptedException

Specified by:

getTable in interface BigQueryServices.DatasetService

Throws:

IOException

InterruptedException

createTable

public void createTable(Table table)
                 throws InterruptedException,
IOException

Creates the specified table if it does not exist.

If a table with the same name already exists in the dataset, the function simply returns. In such a case, the existing table doesn't necessarily have the same schema as specified by the parameter.

Specified by:

createTable in interface BigQueryServices.DatasetService

Throws:

IOException - if other error than already existing table occurs.

InterruptedException

deleteTable

public void deleteTable(TableReference tableRef)
                 throws IOException,
InterruptedException

Deletes the table specified by tableId from the dataset. If the table contains data, all the data will be deleted.

Tries executing the RPC for at most MAX_RPC_RETRIES times until it succeeds.

Specified by:

deleteTable in interface BigQueryServices.DatasetService

Throws:

IOException - if it exceeds MAX_RPC_RETRIES attempts.

InterruptedException

isTableEmpty

public boolean isTableEmpty(TableReference tableRef)
                     throws IOException,
InterruptedException

Description copied from interface: BigQueryServices.DatasetService

Returns true if the table is empty.

Specified by:

isTableEmpty in interface BigQueryServices.DatasetService

Throws:

IOException - if the table is not found.

InterruptedException

getDataset

public Dataset getDataset(String projectId,
 String datasetId)
                   throws IOException,
InterruptedException

Gets the specified Dataset resource by dataset ID.

Tries executing the RPC for at most MAX_RPC_RETRIES times until it succeeds.

Specified by:

getDataset in interface BigQueryServices.DatasetService

Throws:

IOException - if it exceeds MAX_RPC_RETRIES attempts.

InterruptedException

createDataset

public void createDataset(String projectId,
 String datasetId,
 @Nullable String location,
 @Nullable String description,
 @Nullable Long defaultTableExpirationMs)
                   throws IOException,
InterruptedException

Create a Dataset with the given location, description and default expiration time for tables in the dataset (if null, tables don't expire).

Tries executing the RPC for at most MAX_RPC_RETRIES times until it succeeds.

Specified by:

createDataset in interface BigQueryServices.DatasetService

Throws:

IOException - if it exceeds MAX_RPC_RETRIES attempts.

InterruptedException

deleteDataset

public void deleteDataset(String projectId,
 String datasetId)
                   throws IOException,
InterruptedException

Deletes the dataset specified by the datasetId value.

Before you can delete a dataset, you must delete all its tables.

Tries executing the RPC for at most MAX_RPC_RETRIES times until it succeeds.

Specified by:

deleteDataset in interface BigQueryServices.DatasetService

Throws:

IOException - if it exceeds MAX_RPC_RETRIES attempts.

InterruptedException

insertAll

public <T> long insertAll(TableReference ref,
 List<FailsafeValueInSingleWindow<TableRow,TableRow>> rowList,
 @Nullable List<String> insertIdList,
 InsertRetryPolicy retryPolicy,
 List<ValueInSingleWindow<T>> failedInserts,
 ErrorContainer<T> errorContainer,
 boolean skipInvalidRows,
 boolean ignoreUnknownValues,
 boolean ignoreInsertIds,
 List<ValueInSingleWindow<TableRow>> successfulRows)
                   throws IOException,
InterruptedException

Description copied from interface: BigQueryServices.DatasetService

Inserts TableRows with the specified insertIds if not null.

If any insert fail permanently according to the retry policy, those rows are added to failedInserts.

Returns the total bytes count of TableRows.

Specified by:

insertAll in interface BigQueryServices.DatasetService

Throws:

IOException

InterruptedException

getErrorInfo
