Hive allows casting TIMESTAMP type to DECIMAL type, which casts the timestamp into unix time with decimal type.
Trino/Presto does not allow for this kind of casting, and attempting the same query results in
Cannot cast timestamp to decimal(10,0)
So we propose mapping
CAST(timstamp_col AS DECIMAL(10,0))
To
CAST("to_unixtime"(timstamp_col) AS DECIMAL(10,0))
In order to achieve the same behavior.
