The data entry is the key/value pair where you store your data. You can manage your entries individually and in batches. To use domain objects for your entry values and keys, you need to follow Apache Geode requirements for data storage and distribution.
Program your applications to create, modify, and manage your cached data entries.
Set the copy-on-read region attribute to cause operations that get data to make a copy of the data, instead of returning a reference to the data.
Follow these guidelines to use custom domain classes for your cached entry keys and values.
