> When call the function S2GraphHelper.initS2Graph() , S2Graph is initialized 
> every time.
> It causes initialize the Model class, so many connections can be created to 
> DB.
> In especially, when you call writeBatchWithMutate on the S2graphSink class, 
> the following code initializes S2Graph for each task.
> {code:java}
> df.foreachPartition { iters =>
>   val config = ConfigFactory.parseString(serializedConfig)
>   val s2Graph = S2GraphHelper.initS2Graph(config)
>   ...
> }
> {code}
>  
> I think it would be better if we can re-use S2Graph instance on the same 
> executor.
