xiaojian zhou commented on GEODE-6428:
--------------------------------------
The following types of objects that wrapped the byte array. We can get rid of
them to save another 100 bytes:
HeapByteBuffer, PdxInputStream, ByteBufferByteSource
> PdxInstanceFactory could be optimized to use less memory

> Key: GEODE-6428
> URL: https://issues.apache.org/jira/browse/GEODE-6428
> Project: Geode
> Issue Type: Improvement
> Components: serialization
> Reporter: Darrel Schneider
> Priority: Major
>
> https://issues.apache.org/jira/browse/GEODE-6414 was able to reduce the
> amount of memory consumed by the PdxInstance. Further optimizations can be
> done by getting rid of some of the extra objects that wrap the byte array
> owned by the PdxInstance. If the factory is creating an instance that will
> never deserialize then optimizing the memory usage of the PdxInstance is more
> likely to be of value.
> It seems like an alternative implementation to PdxInstanceImpl could be a
> class that just has a byte[] reference, an PdxType reference, and an "int"
> for the hashCode. For some operations you might need to use this information
> to create a full fledged PdxInstanceImpl at runtime but having the one with
> the smaller footprint could save around 100 bytes per PdxInstance.
