> 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: Plasma (C++)
> Reporter: Robert Nishihara
> Assignee: Robert Nishihara
> Priority: Major
> Labels: pull-request-available
>
> 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.
