df = ctx.sql("""
select
* EXCLUDE("I","XX","SETTLEMENTDATE"),
CAST(to_timestamp_seconds("SETTLEMENTDATE",'%Y/%m/%d
%H:%M:%S') AS TIMESTAMP(6)) as SETTLEMENTDATE,
cast(EXTRACT(YEAR FROM
CAST(to_timestamp_seconds("SETTLEMENTDATE",'%Y/%m/%d %H:%M:%S') AS
TIMESTAMP(6))) as integer) as year
from arrow_dataset
where "I" ='D' and "UNIT"='DUNIT' and "VERSION" ='3'
""")
write_deltalake(f"{table_root}/T{total_files}/datafusion",
df,mode="overwrite",partition_by=['year'])
