> Problem
> Thread leak in compaction operation if prefetch is enabled and compaction process is killed
> Analysis
> During compaction if prefetch is enabled RawResultIterator launches an executor service for prefetching the data.
> If compaction fails or the process is killed it can lead to thread leak due to executor service still in running state.
