---------------------------------------
Summary: 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
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.
