Description

This is in response to the discussion in https://github.com/apache/arrow/pull/6323#issuecomment-614195070

In this issue, we provide an allocation manager that is capable of allocation large (> 2GB) buffers. In addition, it does not depend on the netty library, which is aligning with the general trend of removing netty dependencies. In the future, we are going to make it the default allocation manager.
