Hello and welcome to the Airbyte community, @vaibhavpals! Could you show me the server logs that you’re getting? We’ve gotten a few similar issues to this one recently, and this might help me point you to a solution.

Can you guide me as to exactly what logs i need to be looking at?
Which container should I monitor? And detailed logging i need to enable?


I believe this to be the error :
io.grpc.StatusRuntimeException: RESOURCE_EXHAUSTED: grpc: received message larger than max (4676324 vs. 4194304)

Thanks for posting the error. Currently Airbyte supports up to 6000 tables; it’s on our roadmap to expand that number, but I can’t give you a definitive date on when 6000+ tables will be supported yet. If you’d like to keep an eye on this, here is the related issue:
