    +# Geode partitioned region example
    +This example demonstrates the basic property of partitioning, as well
    +as what can go wrong with partitioned regions. 
    +The example is presented in two parts.
    +The first part shows partitioning, and the second part demonstrates
    +what can go wrong with a flawed implementation.
    +The basic property of partitioning is that data entries are distributed 
    +across all servers that host a region.
    +The distribution is like database sharding, except that the distribution
    +occurs automatically. It is also similar to data striping on disks,
    +except that the distribution is not based on hardware.

    I don't think this "disk striping" analogy really helps.

> Add a new example to the geode-examples that demonstrates partitioning.
> The example will use the same structure as the replicated example, starting 2 servers
that host a partitioned region (with no redundant copies).  Run the producer to populate the
region.  Run the consumer to see the contents of the region. Then, stop one of the servers
and run the consumer again to notice that only roughly half (with 2 servers and hopefully
a reasonable hash) of the entries are present.
