how to delete data and write the new data using saveAsBigQueryTable

[Ayyappadas1]

Hi

Is there any way we can purge the old data from the Bigquery table and write new set of data to Bigquery table?

Thanks

Something like this?

writeDisposition = WriteDisposition.WRITE_TRUNCATE, 
   createDisposition = CreateDisposition.CREATE_IF_NEEDED
