[jira] [Created] (ARROW-12749) [C++] Unnecessary copy cause by constructing RecordBatch/Table/Schema from lvalues

Yibo Cai created ARROW-12749:
--------------------------------

             Summary: [C++] Unnecessary copy cause by constructing RecordBatch/Table/Schema from lvalues
                 Key: ARROW-12749
                 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.
