@Yohahaha @FelixYBW, Velox has a similar function also called `split_part` in prestosql folder. A long time ago, we noted this function has some difference from Spark's. So we put it into black list to avoid using that Velox function.
@Yohahaha, would you like to implement Spark's `split_velox` in Velox? Maybe, you can do that based on presto's implementation. And in Gluten, we may need to revert Spark's runtime replacement, i.e., use `split_part` for `element_at(StringSplitSQL)`, then offloading to Velox's `split_part`.
