> Project: IMPALA

> Assignee: Alex Rodoni
> Priority: Major

> A single impala executor with a lower memory limit than the rest can easily
> become a bottleneck and lead to suboptimal performance. We should mention
> having consistent memory allocations across backends.
> Note that this does not apply to coordinator-only nodes.
