Tsz Wo Nicholas Sze created HDDS-293:
----------------------------------------

             Summary: Reduce memory usage in KeyData
                 Key: HDDS-293
                 URL: https://issues.apache.org/jira/browse/HDDS-293
             Project: Hadoop Distributed Data Store
          Issue Type: Improvement
            Reporter: Tsz Wo Nicholas Sze
            Assignee: Tsz Wo Nicholas Sze


Currently, the field chunks is declared as a List<ChunkInfo> in KeyData as shown below.
{code}
//KeyData.java
  private List<ContainerProtos.ChunkInfo> chunks;
{code}
It is expected that many KeyData objects only have a single chunk.  We could reduce the memory usage.
