             Summary: Compact buffers of ExpandableMarshalledValueByteStream to save memory on long term storage
                 Key: ISPN-2189
                 URL: https://issues.jboss.org/browse/ISPN-2189
             Project: Infinispan
          Issue Type: Enhancement
    Affects Versions: 5.1.5.FINAL
            Reporter: Sanne Grinovero
            Assignee: Manik Surtani
             Fix For: 5.2.0.ALPHA3


Buffers allocated by org.infinispan.io.ExpandableMarshalledValueByteStream grow by approximation, but in

{code}org.infinispan.marshall.MarshalledValue.serialize0(){code}

we know when the buffer won't grow any longer as it's going to be treated as effectively immutable. At this point we should shrink the buffer to potentially save memory on each entry in the datagrid.

This likely needs to be optional as depending on configuration the buffer might be used for a temporary operation, in which case the effort of resizing should be avoided.
