问题 I am using GraphQl APIs in the react-native chat application. I want to get real-time updates when another user sends a message to me without refreshing the API. How can I do it using GraphQl API using GraphQl subscriptions or Websocket in react-native? Should I use different URLs for subscription and normal API's? Here is my config.js import { ApolloClient } from 'apollo-client'; import { createHttpLink } from 'apollo-link-http'; import { WebSocketLink } from 'apollo-link-ws'; import {

问题 my company has a messaging system which sends real-time messages in JSON format, and it's not built on AWS, and will not have any VPN connection with AWS. our team is trying to use AWS SQS to receive these messages, which will then have DynamoDB process JSON messages to TSV, then load into RDS. however, as per the FAQ, SQS can only receive message from within AWS. https://aws.amazon.com/sqs/faqs/ Q: Who can perform operations on a message queue?

问题 I'm trying to implement a Spring Boot-based Kafka consumer that has some very strong message delivery guarentees, even in a case of an error. messages from a partition must be processed in order, if message processing fails, the consumption of the particular partition should be suspended, the processing should be retried with a backoff, until it succeeds. Our current implementation fulfills these requirements: @Bean public KafkaListenerContainerFactory<ConcurrentMessageListenerContainer

问题 I have gone through different questions/articles on Message Brokers and ESBs(Even on stackoverflow). Still not a clue as what is the CLEAR demarcating difference between an Message Broker and an ESB? Now here I am trying to compare products, Websphere Broker and Mule ESB!! Firstly , is (any version) Webshere Broker an ESB? Our IBM product guys claims it to be an ESB!(I am not surprised about that). My limited information tells me that a Message Broker works on a HUB-SPOKE model. However the

问题 This question is about architecture and kafka topics migrating. Original problem : schema evolution without backward compatibility. https://docs.confluent.io/current/schema-registry/avro.html I am asking the community to give me an advice or share articles from which I can get inspired and maybe think of a solution to my problem. Maybe there is an architecture or streaming pattern. It is not necessary to give me a language specific solution; just give me a direction into which I can go... My

问题 How does AMQP overcome the difficulties of using TCP directly when sending messages? Or more specifically in a pub/sub scenario? 回答1: In AMQP there is a broker, that broker receives the messages and then does the hard part about routing them to exchanges and queues. You can also setup durable queues which save the messages for clients even when they are disconnected. You could certainly do all this yourself, but it's a tremendous amount of work to do correctly. RabbitMQ in particular has been
