> Fix For: 0.9
>
>
> Currently, the memory manager pre-allocates all memory.
> We should introduce an option where it allocates bytes as needed and releases
> them when not needed any more. This will allow us to run streaming jobs and
> batch jobs concurrently, without blocking the memory for the streaming jobs.
