Gang Wu commented on ARROW-15289:
---------------------------------

Hi [~wesm] [~apitrou], is it a valid use case to support mutable arrow RecordBatch / Array C++ interfaces? We have implemented it and depended on it extensively at Alibaba. If true, we are happy to contribute it back to the community. Thanks!

> For scenarios where the record batch needs to be reused, the repeated construction of record batch is expensive. This task is about supporting a mutable recordBatch/array to avoid repeated construction overhead.
