Zhijun Fu created ARROW-4711: -------------------------------- Summary: [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
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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
