             Summary: [Plasma] Support setting memory quotas per plasma client for better isolation
                 Key: ARROW-5955
                 URL: https://issues.apache.org/jira/browse/ARROW-5955
             Project: Apache Arrow
          Issue Type: Improvement
            Reporter: Eric Liang


Currently, plasma evicts objects according a global LRU queue. In Ray, this often causes memory-intensive workloads to fail unpredictably, since a client that creates objects at a high rate can evict objects created by clients at lower rates. This is despite the fact that the true working set of both clients may be quite small.
