@Ujjwal9235 not sure I understand the question. AWS AppSync is a service that provides GraphQL interface to databases.

Maybe you meant other service like AWS EventBridge? If not, can you elaborate on your use case?

@debora-ito I want to make a real-time java application with appsync in 100% Java, and for that I need java client which will able to subscribe and listen the message and print the message, whenever there will be any mutation.
