Subject [jira] [Created] (GEODE-6428) PdxInstanceFactory could be optimized to use less memory
Date Tue, 19 Feb 2019 21:38:00 GMT
Darrel Schneider created GEODE-6428:

             Summary: PdxInstanceFactory could be optimized to use less memory
                 Key: GEODE-6428
             Project: Geode
          Issue Type: Improvement
          Components: serialization
            Reporter: Darrel Schneider 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.
