We have added the TD_DIVIDE UDF to the Hive engine, which makes the division of numeric types safer even when the denominator is zero. If the denominator is zero, it returns 0; in all other cases it returns the result of the division between the 2 arguments as expected.

See the documentation page for more info: TD_DIVIDE(num, den)


We have added the TD_SUBSTRING_INENCODING UDF to the Hive engine; it returns the substring or slice of the byte array in input from the 0-index position at most max_len_inbytes with charset encoding. charset is one of those indicated here: java.nio.charset.Charset.

See the documentation page for more info: TD_SUBSTRING_INENCODING(column, length, charset)
