Robert Yokota updated KAFKA-6894:
---------------------------------
Description:
I was trying to access a store from a {{GlobalKTable}} in
{{KStream.transform()}}, but I got the following error:
{code}
org.apache.kafka.streams.errors.TopologyException: Invalid topology: StateStore
globalStore is not added yet.

{code}
I have submitted a PR to improve the error message.

I was able to make a change to
{{InternalTopologyBuilder.connectProcessorAndState}} to allow me to access the
global store from {{KStream.transform()}}. I will submit a PR for review.
Summary: Improve error message when connecting processor with a global
store (was: Cannot access GlobalKTable store from KStream.transform())
