Neal Richardson updated ARROW-7012:
-----------------------------------
Priority: Minor (was: Major)
> [C++] Clarify ChunkedArray chunking strategy and policy
> -------------------------------------------------------
>
> Key: ARROW-7012
> URL: https://issues.apache.org/jira/browse/ARROW-7012
> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++
> Reporter: Neal Richardson
> Assignee: Wes McKinney
> Priority: Minor
> Fix For: 1.0.0
>
>
> See discussion on ARROW-6784 and [https://github.com/apache/arrow/pull/5686].
> Among the questions:
> * Do Arrow users control the chunking, or is it an internal implementation
> detail they should not manage?
> * If users control it, how do they control it? E.g. if I call Take and use a
> ChunkedArray for the indices to take, does the chunking follow how the
> indices are chunked? Or should we attempt to preserve the mapping of data to
> their chunks in the input table/chunked array?
> * If it's an implementation detail, what is the optimal chunk size? And when
> is it worth reshaping (concatenating, slicing) input data to attain this
> optimal size?
