Gengliang Wang updated SPARK-41456:
-----------------------------------
Description:
For try_cast and the legacy cast (cast with ANSI SQL mode off), there are
conversion which has the same behaviors:
* cast(string as date/timestamp/TimestampNTZ)
* cast(string as double/float/decimal)
So, the try_cast can be faster if it uses the evaluation code path of the
legacy cast, instead of turning into ANSI cast and catching exceptions.
> Improve the performance of try_cast
