> This jira covers work done to improve Drill's handling of memory. Specifically, this includes:
> Allow trimming of buffers after the data has been written, so that unused memory can be returned to the pool.
> Handle case attempts to write beyond a buffers capacity.
> Handle case where a buffer allocator is unable to allocate a new buffer due to memory constraints
> Dynamically adjust allocation sizes based on trends
