[PR] fix oom when plan is large [incubator-gluten]
boneanxs opened a new pull request, #11652:
URL: https://github.com/apache/incubator-gluten/pull/11652
This PR fixes an OOM issue in transition error handling by making `Transition.Factory.findTransition(..., otherwise)` lazy and by avoiding full-plan stringification in `Transition.notFound`.
`otherwise` was passed by value (otherwise: Exception), so `Transition.notFound(...)` was constructed eagerly at call sites.
`notFound` previously interpolated `$plan`, which triggers full `SparkPlan.toString()` and can allocate huge strings for large plans, causing:
