Wes McKinney created ARROW-34:
---------------------------------
Summary: C++: establish a basic function evaluation model
Key: ARROW-34
URL: https://issues.apache.org/jira/browse/ARROW-34
Project: Apache Arrow
Issue Type: New Feature
Components: C++
Reporter: Wes McKinney
We don't exactly have a working model for executing functions on Arrow objects
that require memory allocations (either for intermediate storage of results).
For example:
F(input1, input2) -> output
Since the output type may depend on the input types, F in general will need to
be able to request memory to be allocated. This will have to be figured out
(some sort of ArrowContext with a memory pool attached) in due course. For
example:
F(ctx, input1, input2) -> output
Where ctx is a Context object provided access to memory resources and other
system state (user-configurable).
