ASF GitHub Bot updated ARROW-11680:
-----------------------------------
Labels: pull-request-available (was: )
> [C++] Add vendored version of folly's spsc queue
> ------------------------------------------------
>
> Key: ARROW-11680
> URL: https://issues.apache.org/jira/browse/ARROW-11680
> Project: Apache Arrow
> Issue Type: Sub-task
> Components: C++
> Reporter: Weston Pace
> Assignee: Weston Pace
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Rationale for vendoring:
> Folly contains hundreds of files, requires boost & C++14. The
> ProducerConsumerQueue class could be extracted out of three of those files
> and hasn't been changed since 2018. The queue does not appear to have any
> open issues.
> Comparisons with alternatives:
> I have included a benchmark comparing folly with boost (since
> boost::lockfree::spsc_queue is already included in arrow, I think). Boost
> does not support a move workflow for spsc_queue and performs worse.
> I have not compared with any other alternatives but the utility is small and
> straightforward enough I am doubtful there would be significant differences.
