> The current WanCopyRegionFunctionDelegate may cause significant memory issues in with really large regions.
> The [getEntries|https://github.com/apache/geode/blob/develop/geode-wan/src/main/java/org/apache/geode/management/internal/cli/functions/WanCopyRegionFunctionDelegate.java#L102] method returns both primary and redundant Region Entries for local server.
> The invocation of getEntries from the PartitionedRegionDataStore will cause all entries to be deserialized https://github.com/apache/geode/blob/develop/geode-core/src/main/java/org/apache/geode/internal/cache/PartitionedRegionDataStore.java#L2501-L2515
> The [createBatch|https://github.com/apache/geode/blob/develop/geode-wan/src/main/java/org/apache/geode/management/internal/cli/functions/WanCopyRegionFunctionDelegate.java#L107-L108] method creates a List<GatewayQueueEvent> equally that of the local Region size.
> Essentially ... In a system with VERY large regions this might cause significant memory issues
