[jira] [Created] (CASSANDRA-7133) yield in SlabAllocator$Region.allocate could cause starvation

Jeremiah Jordan created CASSANDRA-7133:
------------------------------------------

             Summary: yield in SlabAllocator$Region.allocate could cause starvation
                 Key: CASSANDRA-7133
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7133
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Jeremiah Jordan
            Assignee: Benedict
            Priority: Minor


If a low priority thread inserts data into a table, it is possible the yield in org.apache.cassandra.utils.SlabAllocator$Region.allocate() could starve.  We already changed this in CASSANDRA-5549 to not yield any longer.  It might be good to back port some of those changes to 2.0 if they aren't too large.
