--------------------------------
Summary: [C++] Unnecessary copy cause by constructing
RecordBatch/Table/Schema from lvalues

URL: https://issues.apache.org/jira/browse/ARROW-12749
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Yibo Cai
Assignee: Yibo Cai
Noticed some codes don't move lvalue augment when constructing
RecordBatch/Table/Schema. It may cause unnecessary data copying, especially
std::vector<std::shared_ptr> which can be big.
