[GitHub] [doris] dataroaring opened a new pull request, #12592: (storage) Level1Iterator should release iterators in heap
dataroaring opened a new pull request, #12592:
URL: https://github.com/apache/doris/pull/12592
When there is a query with limit, e.g. select * from limit 1, scanners are closed by FragmentExecutor, then some scanners do not run to eof and mem leaks happen.
We have to release iterators in the heap.
