-----------------------------------
Summary: [C++][Dataset] Implement InMemoryDatasetFactory
Key: ARROW-7945
URL: https://issues.apache.org/jira/browse/ARROW-7945
Project: Apache Arrow
Issue Type: Improvement
Components: C++, C++ - Dataset
Affects Versions: 0.16.0
Reporter: Ben Kietzman
Assignee: Ben Kietzman
Fix For: 1.0.0
This will allow in memory datasets (such as tables) to participate in discovery
through {{UnionDatasetFactory}}. This class will be trivial since Inspect will
do nothing but return the table's schema, but is necessary to ensure that the
resulting {{UnionDataset}}'s unified schema accommodates the table's schema
(for example including fields present only in the table's schema or emitting an
error when unification is not possible)
