-------------------------------------------------------------
We'd need to clarify our shared memory model. For example,
o Can the same segment be attached at the same address in all prodesses?
(allows embedded pointers vs offsets)
o Platform specific page size (Huge or otherwise)
(necessary on x86 to keep page tables to a reasonable size)

> Issue Type: New Feature
> Reporter: Jacques Nadeau
>
> Because of the focus on the memory format of ValueVectors, Drill could
> benefit from being able to operate across processes using shared memory.
> This would be useful in various storage engines such HBase and could also be
> useful where Drill might be running unsafe code such as when running an
> untrusted UDF. Rather than requiring each implementer to build their own
> interfaces, we should provide some higher level shared tools for this purpose.
