Not sure if parallel option is available in geode version 1.2 for partitioned regions so it means it will export data serially to a single file?
Are you saying that Partitioned Region and its copies are created on all 12 nodes (in the cluster). Yes Are you expecting it all the buckets to be created on one member? No I was expecting it to load balanced across nodes as you said but if I specify total 3 copies why it is creating copies on all data nodes?
