Barry Oglesby created GEODE-2823:
------------------------------------
Summary: The LuceneEventListener caues deserialized values to be
stored in the entry when the region contains DataSerializable or Serializable
values
Key: GEODE-2823
URL: https://issues.apache.org/jira/browse/GEODE-2823
Project: Geode
Issue Type: Bug
Components: lucene
Reporter: Barry Oglesby
If the {{Region}} contains {{DataSerializable}} or {{Serializable}} values,
then each {{RegionEntry}} contains a {{VMCachedDeserializable}}. When
{{LuceneEventListener.process}} calls {{entry.getValue()}}, the value is
deserialized and left in that state in the {{VMCachedDeserializable}}.
Below is a live histogram for the no index test.
