>                 Key: ARROW-7280
>                 URL: https://issues.apache.org/jira/browse/ARROW-7280
>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: Documentation, Java, Python
>            Reporter: Vinay
>            Priority: Major
>
> There are limited references for Arrow Flight implementation/examples for 
> DataStores.
> For holding huge data it may require to choose memory mapped file/file system 
> instead of unsafe memory buffer.
> It will be great if any there is any reference in this direction for JAVA and 
> Python API.
>  
> And also the possibility if this is feasible with performance.
