baibaichen opened a new issue, #11913:
URL: https://github.com/apache/gluten/issues/11913
## Backend
VL (Velox)
## Bug description
`split('hello', '', 1)` returns `["h"]` in Velox but should return
`["hello"]`. This is a Velox C++ re2-based split implementation issue when the
`limit` parameter is specified. Spark 4.1 added the `limit` parameter test via
SPARK-49968.
Spark 4.1 only.
Parent issue: #11550
