Gemfire simple client

This is a simple Gemfire client which just populate some informations in regions.

Regions are populated by Italian cars (Alfa Romeo, FCA, Lancia)

Useful as demo or POC

Before starting it you mush create a Gemfire cluster

Start a simple (non production ready) gemfire locator and a gemfire cache server and enable pdx

start locator --name=locator0 --port=10334</br>
configure pdx --read-serialized=true</br>
start server --name=node0 --locators=localhost[10334] --initial-heap=5g --max-heap=5g  --critical-heap-percentage=90 --eviction-heap-percentage=80  --use-cluster-configuration=true</br>

Create now the regions Cars and Manufacturers:

create region --name=Cars --type=LOCAL
create region --name=Manufacturers --type=LOCAL

Run the software (find in target directory the already compiled .jar) you should now see the regions populated in this way:
