Hi,

I am Dong Yang, and my apache account is twosand.  What we are using Gemfire is 
not commonly usage scenario in other company, it's more like a OLTP and OLAP 
mixed scenario. The concept is very similar to using Spark-Gemfire connect, we 
have some server-side function that can shuffle data from server to client as 
stream style. And we encountered the thread lock issue in different 
environments. Before we use Gemfire8 , now we are upgrading to GemFrie9.
About GEODE-5896, it's very important usage for us, and I think the same for 
others if they want using spark to connect to Gemfire. Now we just do some 
patch at client-side the force the meta ready before function executed. But the 
perfect solution should fix some sever-side code.
I can share what I found and where I want to fix, you can review it , resonale 
or not . Fix it by current geode team or I can do it as a contributor.



Dong Yang, Dong [GTSUS Non-J&J
Thanks
