Calculating the Size of an Apache Geode Region

Introduction

Calculating the size of an Apache Geode Region can be useful for capacity planning. While certain statistics like PartitionedRegionStats dataStoreBytesInUse are helpful in this regard, they are limited. For example, this statistic does not exist for replicated Regions. ObjectGraphSizer can be used to calculate the size of any object in bytes and to create a histogram of the object being sized. It does this by recursively traversing each field of the object.
