> Project: Apache Drill
> Issue Type: Task
> Affects Versions: 1.11.0
> Reporter: Paul Rogers

> Fix For: 1.11.0
>
>
> Rollup of a set of specific JIRA entries that all relate to the very
> difficult problem of managing memory within Drill in order for the external
> sort to stay within a memory budget. In general, the fixes relate to better
> estimating memory used by the three ways that Drill allocates vector memory
> (see DRILL-5522) and to predicting the size of vectors that the sort will
> create, to avoid repeated realloc-copy cycles (see DRILL-5594).
