withDataSourceConfiguration

public JdbcIO.Write<T> withDataSourceConfiguration(JdbcIO.DataSourceConfiguration config)

withStatement

public JdbcIO.Write<T> withStatement(java.lang.String statement)

withStatement

public JdbcIO.Write<T> withStatement(ValueProvider<java.lang.String> statement)

withPreparedStatementSetter

public JdbcIO.Write<T> withPreparedStatementSetter(JdbcIO.PreparedStatementSetter<T> setter)

withBatchSize

public JdbcIO.Write<T> withBatchSize(long batchSize)

Provide a maximum size in number of SQL statenebt for the batch. Default is 1000.

Parameters:

batchSize - maximum batch size in number of statements

withRetryStrategy

public JdbcIO.Write<T> withRetryStrategy(JdbcIO.RetryStrategy retryStrategy)

When a SQL exception occurs, JdbcIO.Write uses this JdbcIO.RetryStrategy to determine if it will retry the statements. If JdbcIO.RetryStrategy.apply(SQLException) returns true, then JdbcIO.Write retries the statements.

expand

public PDone expand(PCollection<T> input)

Description copied from class: PTransform

Override this method to specify how this PTransform should be expanded on the given InputT.

NOTE: This method should not be called directly. Instead apply the PTransform should be applied to the InputT using the apply method.

Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).
