------------------------------
    External issue URL: https://github.com/apache/arrow/issues/17982

> Deduplicate file descriptors when plasma store replies to get request.
> ----------------------------------------------------------------------
>
>                 Key: ARROW-2000
>                 URL: https://issues.apache.org/jira/browse/ARROW-2000
>             Project: Apache Arrow
>          Issue Type: Bug
>          Components: C++ - Plasma
>            Reporter: Robert Nishihara
>            Assignee: Robert Nishihara
>            Priority: Major
>              Labels: pull-request-available
>             Fix For: 0.9.0
>
>
> Right now when the plasma store replies to a GetRequest from a client, it sends many file descriptors over the relevant socket (by calling {{send_fd}}). However, many of these file descriptors are redundant and so we should deduplicate them before sending.
>  
> Note that I often see the error "Failed to send file descriptor, retrying." printed when getting around 100 objects from the store. This may alleviate that.
