@ibrahim Thank you so much for quick response as always. Thanks for clarifying the export part.
During schema update, I got “connection refused” while dialling for alpha through grpc, but I am not sure whether they are only due to the schema update happening, as in my environment, they can be very well due to the exceeding open file limits of the system. I am trying a few more things on this part, I will post here if I find some evidence that the reads indeed failed due to the schema update.
