---------------------------------------
Summary: 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
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.
