How to create a table in BigQuery with Partitioning and clustering via DDL command?

The following code snippet is the answer, however, be very careful about what you choose as cluster fields as this may cause unintended performance and costs penalties

CREATE TABLE my_dataset.new_clustered_table 
date DATE, 
field_a STRING, 
field_b STRING, 
field_c STRING, 
field_d STRING, 
field_e STRING ) 
CLUSTER BY field_a, field_b 
OPTIONS ( description="a_table clustered_by_two_fields" )
