Rok Mihevc updated ARROW-4711:
------------------------------
External issue URL: https://github.com/apache/arrow/issues/15997
> [Plasma] enhance plasma client interfaces to work with multiple objects
> ------------------------------------------------------------------------
>
> Key: ARROW-4711
> URL: https://issues.apache.org/jira/browse/ARROW-4711
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++ - Plasma
> Reporter: Zhijun Fu
> Priority: Minor
>
> Right now the Delete() interface in plasma client supports deleting multiple
> objects in a single shot, so that we can save IPCs (inter-processing
> communication) between plasma clients and plasma store. This reduces latency
> for plasma clients, and also improve the actual throughput for plasma store.
> I made a simple prototype for changing Release() function as well, when
> batching release 10 objects in a single IPC, it only takes about 1/6 of the
> time compared with using 10 separate IPCs. Also from profiling, processing
> IPCs takes a lot of CPU cycles in plasma store currently, as UNIX domain
> socket processing needs to go through kernel, thus batching multiple IPCs
> into a single one should greatly improve the plasma store performance as well.
>
> This change mostly applies to Release(), Seal(), and Create() interfaces.
